XC9140 Series ETR04015-009c Step-Up Synchronous PFM DC/DC Converter ☆Green Operation Compatible ■ GENERAL DESCRIPTION The XC9140 series are step-up synchronous DC/DC converters that support ceramic capacitors and have an internal 0.6Ω Nch driver transistor and an internal 0.65Ω Pch synchronous rectifier switch transistor. PFM control enables a low quiescent current, making these products ideal for portable devices that require high efficiency. When the output voltage is 3.3V and the load current is 1mA, startup from an input voltage of VIN = 0.9V is possible which means that these products can be used in applications that start using a single alkaline or nickel-metal hydride battery. A version with a UVLO (Under Voltage Lock-out) function is also available. This function enables the reduction of battery leakage by stopping IC’s operation when the input voltage is low. The standard product has a UVLO release voltage of 1.65V, 2.15V and a custom version with a release voltage selectable from between 1.65V to 2.2V, in steps of 0.05V, is also available. ■FEATURES ■APPLICATIONS ● ● ● ● ● ● Mouses, Keyboards Bluetooth Household use Medical equipments Remote controls Game consoles Devices with 1~3 Alkaline, 1~3 Nickel Hydride, 1 Lithium and 1 Li-ion Input Voltage Range : operating hold voltage 0.7V ~ 5.5V Start-up voltage 0.9V ~ 5.5V Output Voltage Setting : Without UVLO 1.8V ~ 5.0V (±2.0%) Output Current : With UVLO 80mA@VOUT=3.3V, VBAT=1.8V 3.0V ~ 5.0V (±2.0%) Driver Transistor : 0.6Ω Nch driver transistor Supply Current : 6.3μA (VBAT=VOUT+0.5V) Control Method : PFM Control High speed transient response : 50mV@VOUT=3.3V, VBAT=1.8V, IOUT=1→50mA PFM Switching Current : 350mA Functions : Load Disconnection (A,B Type) 0.65Ω Pch synchronous rectifier switch transistor Bypass Mode (C Type) CL discharge (B Type), UVLO Output Capacitor Ceramic Capacitor Operating Ambient Temperature : -40℃ ~ 85℃ Packages : SOT-25, USP-6EL Environmentally Friendly : EU RoHS Compliant, Pb Free ■TYPICAL APPLICATION CIRCUIT ■TYPICAL PERFORMANCE CHARACTERISTICS ●Efficiency vs. Output Current XC9140A331MR-G(VOUT=3.3V) 100 L=4.7μH 2.5V VOUT CL=10μF CE VBAT IN=4.7μF CC IN=10μF GND Efficiency : EFFI (%) LX VIN=0.9~5.5V L=4.7μH(VLF302512M-4R7M),C IN =4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) 80 3.0V 60 VBAT =1.8V 40 20 0 0.01 0.1 1 10 100 1000 Output Current : I OUT (mA) 1/33 XC9140 Series ■ BLOCK DIAGRAM XC9140Axx1/XC9140Cxx1 Type LX PFM CFB RFB1 Parasitic Diode Controller VOUT VOUT Current Sense RFB2 PFM Comparator FB PFM Controller + VREF CE Buffer Driver and Inrush Currrent Protection GND VOUT VDD CE and Bypass Controller Logic VBAT–VOUT Detector VBAT * Diodes inside the circuit are an ESD protection diodes and a parasitic diodes.

LX PFM Comparator Unit CFB RFB1 Parasitic Diode Controller VOUT VOUT Current Sense RFB2 PFM Comparator CL Discharge Buffer Driver and Inrush Currrent Protection FB PFM Controller + GND VOUT VREF CE VDD CE and Bypass Controller Logic Hysteresis UVLO Comparator VBAT–VOUT Detector VBAT + - Current limit PFM control is used for the control method to make it difficult for the output voltage ripple to increase even when the switching current is superimposed, so the product can be used within a wide voltage and current range. Further, because PFM control is used, it has excellent transient response to support low capacity ceramic capacitors to realize a compact, highperformance boost DC/DC converter. The synchronous driver and rectifier switch Tr efficiently sends the coil energy to the capacitor connected to the VOUT pin to achieve highly efficient operation from low to high loads. The electrical characteristics actual output voltage VOUT(E) is the PFM comparator threshold voltage shown in the block diagram. Therefore, the booster circuit output voltage average value, including the peripheral components, depends on the ripple voltage, so this must be carefully evaluated before being used in the actual product. VBAT=VCE=2.0V、VOUT=3.3V、IOUT=20mA、L=4.7μH、CL=10μF、Ta=25℃ VOUT Voltage Average VBAT=VCE=2.0V、VOUT=3.3V、IOUT=70mA、L=4.7μH、CL=10μF、Ta=25℃ VLX VLX VOUT VOUT VLX:2V/div VOUT Voltage V OUT:50mV/div Average ILX:200mA/div VOUT(E) VOUT(E) IPFM ILX ILX 2[μs/div] 2[μs/div] < Reference Voltage Source (VREF)> The reference voltage source (VREF voltage) provides the reference voltage to ensure stable output voltage of the DC/DC converter. < PFM Control > ①The voltage from the output voltage divided by the division resistors RFB1 and RFB2 in the IC is used as feedback voltage (FB voltage), and the PFM comparator is compared with the FB voltage and VREF. If the FB voltage is lower than VREF, the signal is sent to the buffer driver via the PFM control circuit and the Nch driver Tr is turned ON. If the FB voltage is higher than VREF, the PFM comparator sends a signal that does not turn ON the Nch driver Tr. ②The current sense circuit monitors the current flowing in the Nch driver Tr connected to the Lx pin when the Nch driver Tr is ON. When the prescribed PFM switching current (IPFM) is reached, the signal is sent to the buffer driver via the PFM control circuit to turn OFF the Nch driver Tr and turn ON the Pch synchronous rectifier switch Tr. ③The Pch synchronous rectifier switch Tr ON time (off time) is dynamically optimized internally. After the off time has passed, when the PFM comparator confirms the VOUT voltage has exceeded the set voltage, a signal that does not allow the Nch driver Tr to be turned on is sent from the PFM comparator to the PFM control circuit, but if the VOUT voltage remains lower than the set voltage, then Nch driver Tr ON is started. The intervals of the above ①②③ linked operations are continuously adjusted in response to the load current to ensure the output voltage is kept stable from low to high loads and that it is done with good efficiency. 14/33 XC9140 (Design Target) XC9140 Series ■OPERATIONAL EXPLANATION (Continued) The PFM switching current unit monitors the current flowing in the Nch driver Tr and functions to limit the current flowing in the Nch driver Tr, but if the load current becomes much larger than the PFM switching energy, the VOUT voltage becomes lower and prevents the coil current in the Nch driver Tr OFF period from lowering, which affects the internal circuit delay time and results in an excessive current that is larger than the PFM switching current flowing in the Nch driver Tr and Pch synchronous rectifier switch Tr. When a "L" voltage is input to the CE pin, the A/B type enters into standby mode and the C type enters into bypass mode to stop the circuit required for the boost operation. In the standby mode the load cut-off function operates and both the Nch driver Tr and Pch synchronous rectifier switch Tr are turned OFF, which cuts off the current to the LX pin and VOUT pin and the parasitic diode control circuit connects the parasitic diode cathode of the Pch synchronous rectifier switch Tr to the LX pin ①. In the bypass mode the Nch driver Tr is OFF, the Pch synchronous rectifier switch Tr is ON when VLX > VOUT, and the parasitic diode control circuit connects the parasitic diode cathode of the Pch synchronous rectifier switch Tr to the VOUT pin ②. Also, when VLX < VOUT, the Pch synchronous rectifier switch Tr is turned OFF and the parasitic diode cathode is connected to the VOUT pin ②. Note: Except for the moment when the VBAT voltage is input. ① ② Parasitic Diode Controller LX Pin Side VOUT Pin Side Parasitic Diode Controller LX Pin Side VOUT Pin Side Buffer Driver Buffer Driver < VBAT-VOUT Voltage Detection Circuit> The VBAT-VOUT voltage detection circuit compares the VBAT pin voltage with the VOUT pin voltage, and whichever is the highest is operated to become the IC power supply (VDD). In addition, if, during normal operation, the input voltage becomes higher than the output voltage, the Nch driver Tr is turned OFF and the Pch synchronous rectifier switch Tr is kept ON so that the input voltage pass through to the output voltage (through mode). When the input voltage becomes lower than the output voltage, the circuit automatically returns to the normal boost operation. This detection circuit does not operate when in the standby mode. When the VBAT or VCE power supply is input, CL is charged via the stable current that results from the inrush current protection function (refer to graphs below). Therefore, this function minimizes potential over current from the VBAT pin to the VOUT pin. Also, this current value depends on the VBAT voltage. After CL is charged by the aforementioned stable current and VOUT reaches around the VBAT voltage level, the inrush current protection function will be released after several hundred μs ~ several ms and the IC will then move to step-up mode, by pass mode or through mode. Inrush Current Protection Characteristics L=4.7μH(VLF302512M-4R7M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA),IOUT =1mA,Ta=25℃ 600 Inrush Current Protection (mA) 300 550 250 500 200 450 150 400 350 100 300 50 0 0.5 250 1.0 1.5 2.0 2.5 200 3.0 3.0 Input Voltage: V BAT (V) 3.5 4.0 4.5 5.0 5.5 15/33 XC9140 Series ■OPERATIONAL EXPLANATION (Continued) The UVLO function is selectable on the XC9140 series as an option. When the VBAT pin voltage falls below the UVLO detect voltage, the IC stops switching or BYPASS operation and cuts off the current to the LX pin and VOUT pin (UVLO mode). In addition, when the VBAT pin voltage recovers to above the UVLO release voltage, the IC begins operating again. B types can discharge the electric charge at the output capacitor (CL) quickly during standby mode(CE=”L”) via the Nch FET located between VOUT and GND. Electric charge at the output capacitor (CL) is quickly discharged so that it may avoid application malfunction during standby mode. Discharge time of the output capacitor (CL) is set by the CL discharge resistance (RDCHG) and the output capacitor (CL). By setting time constant of a CL discharge resistance value [RDCHG] and an output capacitor value (CL) as τ(τ=CL×RDCHG), discharge time can be the calculated by the following formulas. However, the CL discharge resistance [RDCHG] is depends on the VBAT or VOUT. We recommend that you fully check actual performance. V=VOUT × e - t /τ or t=τIn(VOUT / V) V VOUT t τ CL RDCHG 16/33 : Output voltage after discharge : Output voltage : Discharge time : CL × RDCHG : Capacity value of the load capacitor (CL) : CL Discharge resistance, it depends on the VBAT or VOUT XC9140 (Design Target) XC9140 Series ■NOTE ON USE 1. Be careful not to exceed the absolute maximum ratings for externally connected components and this IC. 2. The DC/DC converter characteristics greatly depend not only on the characteristics of this IC but also on those of externally connected components, so refer to the specifications of each component and be careful when selecting the components. Be especially careful of the characteristics of the capacitor used for the load capacity CL and use a capacitor with B characteristics (JIS Standard) or an X7R/X5R (EIA Standard) ceramic capacitor. 3. Use a ground wire of sufficient strength. Ground potential fluctuation caused by the ground current during switching could cause the IC operation to become unstable, so reinforce the area around the GND pin of the IC in particular. 4. Mount the externally connected components in the vicinity of the IC. Also use short, thick wires to reduce the wire impedance. 5. An excessive current that is larger than the PFM switching current flowing in the Nch driver Tr and Pch synchronous rectifier switch Tr, which could destroy the IC. 6. When in the bypass mode, the internal Pch synchronous rectifier switch Tr turns ON to allow current to flow to the Lx pin and VOUT pin. When an excessive current comes from the VOUT pin when this bypass operates, it could destroy the Pch synchronous rectifier switch Tr. 7. The CE pin does not have an internal pull-up or pull-down, etc. Apply the prescribed voltage to the CE pin. 8. The coil inductance value applicable range is 4.7μH to 10μH, but 4.7μH is recommended because at this value the coil size and DC/DC performance are optimized. If you want to use another inductance value other than 4.7μH but which is in the above applicable range, be sure to carefully evaluate it first before use. 9. At high temperatures, the product performance could vary causing the efficiency to decline. Evaluate this carefully before use if the product will be used at high temperatures. 10. Please note that the leak current of the Pch synchronous rectifier switch Tr during high-temperature standby operation could cause the output voltage to increase. 11. The output voltage ripple effect from the load current causes the output voltage average value to fluctuate, so carefully evaluate this in the actual product before use. 12. When the booster circuit is activated by a low input voltage, during the time until the output voltage reaches about 1.7V, the PFM switching current function might not operate causing the coil current to be superimposed. (See the figure below.)

If the CL capacity or load current becomes excessively large, the output voltage start-up time, when the power is turned on, will increase, so the coil current might be superimposed during the time it takes for the output voltage to become sufficiently higher than the VBAT voltage. 14. If the input voltage is higher than the output voltage, then the circuit automatically enters the through mode. When the input voltage becomes close to the output voltage, there could be repeated switching between the boost mode and through mode causing the ripple voltage to fluctuate. (Refer to the graphic below) VBAT=VCE=3.316V,V OUT=3.412V,IOUT=3mA,L=4.7μH,CL=10μF,Ta=25℃ VOUT VOUT:100mV/div VBAT VBAT:100mV/div VLX VLX:2.0V/div 200[μs/div] 15. If a different power supply is connected from an external source to the IC could be destroyed.

For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded. 17. Torex places an importance on improving our products and their reliability. We request that users incorporate fail-safe designs and post-aging protection treatment when using Torex products in their systems. 18. When the VBAT power supply or VCE power supply is input, if the VOUT pin voltage does not exceed VBAT -0.35V, which can happen due to the load current being more than the inrush protection current, by pass mode operations won’t function correctly. 19. In the case of products with the UVLO function that do not have CL discharge, the output voltage may occasionally rise due to leakage current from the Pch synchronous switch Tr when high-temperature UVLO mode operates. 19/33 XC9140 Series ■NOTE ON USE (Continued) ●Instructions of pattern layouts 1. In order to stabilize VBAT voltage level, we recommend that a by-pass capacitor (CIN) be connected as close as possible to the VBAT and ground pins. 2. Please mount each external component as close to the IC as possible. 3. Wire external components as close to the IC as possible and use thick, short connecting traces to reduce the circuit impedance. 4. Make sure that the ground traces are as thick as possible, as variations in ground potential caused by high ground currents at the time of switching may result in instability of the IC. 5. Internal driver transistors bring on heat because of the transistor current and ON resistance of the driver transistors. ●Recommended Pattern Layout (SOT-25) FRONT BACK ●Recommended Pattern Layout (USP-6EL) FRONT 20/33 BACK XC9140 (Design Target) XC9140 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (1) Efficiency vs. Output Current XC9140A331MR-G(VOUT=3.3V) L=10μH(VLF302512M-100M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) XC9140A331MR-G(VOUT=3.3V) L=4.7μH(VLF302512M-4R7M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) 100 100 2.5V 80 3.0V Efficiency : EFFI (%) Efficiency : EFFI (%) 2.5V VBAT=1.8V 60 40 20 80 60 40 20 0 0.01 0.1 1 10 100 0 0.01 1000 0.1 Output Current : IOUT (mA) 1 10 100 1000 Output Current : IOUT (mA) XC9140A501MR-G(VOUT=5.0V) L=4.7μH(VLF302512M-4R7M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) XC9140A501MR-G(VOUT=5.0V) L=10μH(VLF302512M-100M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) 100 100 4.2V 4.2V 80 3.7V Efficiency : EFFI (%) Efficiency : EFFI (%) 3.0V VBAT=1.8V VBAT=3.0V 60 40 80 VBAT=3.0V 3.7V 60 40 20 20 0 0.01 0.1 1 10 100 0 0.01 1000 0.1 Output Current : IOUT (mA) 1 10 Output Current : IOUT (mA) 100 1000 (2) Output Voltage vs. Output Current XC9140A331MR-G(VOUT=3.3V) L=4.7μH(VLF302512M-4R7M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) XC9140A331MR-G(VOUT=3.3V) L=10μH(VLF302512M-100M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) 3.9 3.7 2.5V Output Voltage : VOUT (V) Output Voltage : VOUT (V) 3.9 3.0V 3.5 3.3 2.5V 3.0V 3.5 3.3 VBAT=1.8V VBAT=1.8V 3.1 3.7 3.1 2.9 2.9 0.01 0.1 1 10 Output Current : IOUT (mA) 100 1000 0.01 0.1 1 10 100 1000 Output Current : IOUT (mA) 21/33 XC9140 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (2) Output Voltage vs. Output Current (Continued) XC9140A501MR-G(VOUT=5.0V) L=4.7μH(VLF302512M-4R7M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) XC9140A501MR-G(VOUT=5.0V) L=10μH(VLF302512M-100M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) 5.6 Output Voltage : VOUT (V) Output Voltage : VOUT (V) 5.6 5.4 4.2V 5.2 5.0 VBAT=3.0V 5.4 4.2V 5.2 5.0 VBAT=3.0V 3.7V 3.7V 4.8 4.8 4.6 4.6 0.01 0.1 1 10 100 0.01 1000 0.1 Output Current : IOUT (mA) 1 10 100 1000 Output Current : IOUT (mA) (3) Ripple Voltage vs. Output Current XC9140A331MR-G(VOUT=3.3V) L=10μH(VLF302512M-100M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) 300 300 250 250 Ripple Voltage : Vr (mV) Ripple Voltage : Vr (mV) XC9140A331MR-G(VOUT=3.3V) L=4.7μH(VLF302512M-4R7M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) 200 150 2.5V VBAT=1.8V 3.0V 100 200 3.0V 2.5V 150 100 50 50 VBAT=1.8V 0 0.01 0.1 1 10 100 0 0.01 1000 Output Current : IOUT (mA) 1 10 100 1000 Output Current : IOUT (mA) XC9140A501MR-G(VOUT=5.0V) L=4.7μH(VLF302512M-4R7M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) XC9140A501MR-G(VOUT=5.0V) L=10μH(VLF302512M-100M),CIN=4.7μF(LMK107BJ475MA), CL=10μF(LMK107BJ106MA) 300 Ripple Voltage : Vr (mV) 300 Ripple Voltage : Vr (mV) 0.1 250 200 150 4.2V 3.7V VBAT=3.0V 250 4.2V 3.7V 200 150 100 100 50 50 VBAT=3.0V 0 0.01 0.1 1 10 Output Current : IOUT (mA) 22/33 100 1000 0 0.01 0.1 1 10 Output Current : IOUT (mA) 100 1000 XC9140 (Design Target) XC9140 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (4) Output Voltage vs. Ambient Temperature XC9140x50x(VOUT=5.0V) 3.6 5.3 3.5 5.2 Output Voltage : VOUT (V) Output Voltage : VOUT (V) XC9140x33x(VOUT=3.3V) 3.4 3.3 3.2 3.1 5.1 5.0 4.9 4.8 3.0 -50 -25 0 25 50 75 4.7 100 -50 -25 Ambient Temperature: Ta(℃) 25 50 75 100 Ambient Temperature: Ta(℃) (5) Supply Current vs. Ambient Temperature (6) Input Pin Current vs. Ambient Temperature XC9140xxx1 XC9140xxx1 20 2.0 VOUT=5.0V 3.0V 18 VOUT=5.0V 3.0V 1.8 Input Pin Current: IBAT (μA) 16 Supply Current: Iq (μA) 0 14 12 10 8 6 1.6 1.4 1.2 1.0 0.8 0.6 4 0.4 2 0.2 0.0 0 -50 -25 0 25 50 75 -50 100 -25 0 25 50 75 100 Ambient Temperature: Ta (℃) Ambient Temperature: Ta (℃) (8) MAX.
