XCL100/XCL101 Series ETR28004-006a Inductor Built-in Step-up “micro DC/DC” Converter ☆Green Operation Compatible ■GENERAL DESCRIPTION The XCL100/XCL101 series is a synchronous step-up micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, h=1.0mm). A stable step-up power supply is configured using only two capacitors connected externally. An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit wiring. The XCL100/XCL101 series can be used in applications that start from a single alkaline or nickel-metal hydride battery because the input voltage range is 0.7V ~ 5.5V. The output voltage can be set from 1.8V to 5.0V (±2.0%) in steps of 0.1V. PFM control enables a low quiescent current, making these products ideal for portable devices that require high efficiency. The XCL100/XCL101 features a load disconnect function to break continuity between the input and output at shutdown (A,B Type), and a bypass mode function to maintain continuity between the input and output (C Type). ■FEATURES ■APPLICATIONS ●Wearable devices Input Voltage Range : Output Voltage Range : Operating hold voltage 0.7V~5.5V Start-up voltage ●Mobile phones, Smart phones ●Mouses, Keyboards 0.9V~5.5V XCL100 3.0V ~ 5.0V (±2.0%) XCL101 1.8V ~ 5.0V (±2.0%) ●Remote controls Output Current : 80mA＠VOUT=3.3V, VBAT=1.8V ●Portable information devices Supply Current : 6.3μA (VBAT=VOUT+0.5V) Control Method : PFM Control PFM Switching Current : 350mA Functions : Load Disconnection or ●Game consoles Bypass Mode CL Discharge ■TYPICAL APPLICATION CIRCUIT Output Capacitor : Ceramic Capacitor Compatible Operating Ambient Temperature : -40ºC ~ 85ºC Package : CL-2025, CL-2025-02 Environmentally Friendly : EU RoHS Compliant, Pb Free ■ TYPICAL PERFORMANCE CHARACTERISTICS XCL101C501BR-G 7　L1 CL 10μF 1 Lx VSS 6 2 VOUT NC 5 3 VBAT CE 4 80 VCE 8　L2 VIN Efficiency:EFFI(%) VOUT 100 4.2V 3.6V 60 VIN= 3.0V 40 20 CIN 10μF (TOP VIEW) “L1 and Lx”, “L2 and VBAT” is connected by PCB pattern.

Further, because PFM control is used, it has excellent transient response to support low capacity ceramic capacitors to realize a compact, high-performance 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.

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. 14/25 XCL100/XCL101 Series ■OPERATION 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 "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 rises up under a start-up condition. ① ② Parasitic Diode Controller LX Pin Side Parasitic Diode Controller VOUT Pin Side 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 passes 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, bypass mode or through mode.

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.

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 embedded coil is optimized for XCL100/XCL101 series. Please do not use for other purposes. 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. When the voltage difference between VIN and VOUT is small, switching energy increases and there is a possibility that the ripple voltage will be too large. And when the ripple voltage becomes big by influence of a load current, please add the CL capacitor. 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.

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,VOUT=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. Refer to the table below for external voltage availability for each product type and operating conditions.

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 postaging protection treatment when using Torex products in their systems. 18/25 XCL100/XCL101 Series ■NOTE ON USE (Continued) 18. With the A Type, when the VBAT 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, step-up mode or through 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. 20. The proper position of mounting is based on the coil terminal ●Instruction 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. 6. As precautions on mounting, please set the mounting position accuracy within 0.05 mm ●Recommended Pattern Layout TOREX XCL101 GND CE IC LX Lx CIN VIN CL GND VOUT ■About the appearance (coil part) (1) Coils are compliant with general surface mount type chip coil (inductor) specifications and may have scratches, flux contamination and the like. 19/25 XCL100/XCL101 Series ■TYPICAL PERFORMANCE CHARACTERISTICS 1) Output Voltage vs. Output Current XCL101C501BR-G XCL101C331BR-G 5.8 Ta=25℃ Output Voltage:V OUT(V) Output Voltage:V OUT(V) 3.7 3.5 3.3 VIN=1.5V 3.1 1.8V 3.0V Ta=25℃ 5.4 5.0 VIN=3.0V 4.6 3.6V 4.2V 4.2 2.9 0.01 0.1 1 10 100 0.01 1000 0.1 1 10 100 1000 Output Current:IOUT (mA) Output Current:IOUT (mA) 2) Efficiency vs. Output Current XCL101C501BR-G 100 100 80 80 60 3.0V 1.8V VIN= 1.5V 40 Efficiency:EFFI(%) Efficiency:EFFI(%) XCL101C331BR-G 4.2V 3.6V 60 VIN= 3.0V 40 20 20 Ta=25℃ Ta=25℃ 0 0.01 0.1 1 10 100 0 0.01 1000 0.1 1 10 100 1000 Output Current:IOUT (mA) Output Current:IOUT (mA) 3) Ripple Voltage vs. Output Current XCL101C501BR-G XCL101C331BR-G Ta=25℃ 160 120 Ripple Voltage:Vr(mV) Ripple Voltage:Vr(mV) 200 VIN=1.5V 1.8V 3.0V 80 40 0 0.01 0.1 1 10 Output Current:IOUT (mA) 20/25 200 100 1000 160 Ta=25℃ VIN=3.0V 3.6V 4.2V 120 80 40 0 0.01 0.1 1 10 Output Current:IOUT (mA) 100 1000 XCL100/XCL101 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) 4) Bypass Voltage vs. Output Current XCL101C331BR-G 3.8 VIN=3.6V CE=0V -40℃ 3.6 Ta=25℃ 3.5 85℃ 3.4 3.3 3.2 3.1 0 50 100 150 200 250 VIN=5.0V CE=0V 5.1 Output Voltage : V OUT (V) 3.7 Output Voltage : V OUT (V) XCL101C501BR-G 5.2 300 5.0 -40℃ Ta=25℃ 4.9 85℃ 4.8 4.7 4.6 4.5 0 50 Output Current: IOUT (mA) 100 150 200 250 300 Output Current: IOUT (mA) 5) Load Transient Response XCL101C331BR-G XCL101C331BR-G IOUT= 1.0mA→50mA IOUT= 50mA→1.0mA VOUT VOUT IOUT =50mA IOUT SW IOUT SW IOUT =50mA IOUT =1.0mA IOUT =1.0mA VBAT=VCE=1.8V, VOUT=3.3V, Ta=25℃, CIN=4.7μF, CL=10μF VBAT=VCE=1.8V, VOUT=3.3V, Ta=25℃, CIN=4.7μF, CL=10μF VOUT:50mV/Div, IOUT SW:1.0V/Div, Time:20μs VOUT:50mV/Div, IOUT SW:1.0V/Div, Time:20μs XCL101C501BR-G XCL101C501BR-G IOUT= 1.0mA→50mA IOUT= 1.0mA→50mA VOUT VOUT IOUT =50mA IOUT SW IOUT =1.0mA IOUT SW IOUT =50mA IOUT =1.0mA VBAT=VCE=3.0V, VOUT=5.0V, Ta=25℃, CIN=4.7μF, CL=10μF VBAT=VCE=3.0V, VOUT=5.0V, Ta=25℃, CIN=4.7μF, CL=10μF VOUT:50mV/Div, IOUT SW:1.0V/Div, Time:20μs VOUT:50mV/Div, IOUT SW:1.0V/Div, Time:20μs 21/25 XCL100/XCL101 Series ■PACKAGING INFORMATION For the latest package information go to, www.torexsemi.com/technical-support/packages PACKAGE OUTLINE / LAND PATTERN THERMAL CHARACTERISTICS CL-2025 CL-2025 PKG CL-2025 Power Dissipation CL-2025-02 CL-2025-02 PKG CL-2025-02 Power Dissipation 22/25 XCL100/XCL101 Series ■MARKING RULE XCL101 ① represents products series MARK PRODUCT SERIES 1 1 ① ② ③ ⑤ 3 ④ 2 6 5 4 XCL101******-G ② represents integer portion of the output voltage XCL101A***** XCL101C***** VOUT (V) MARK VOUT (V) 1.x 2.x 3.x 4.x 5.x 1 2 3 4 5 MARK 1.x 2.x 3.x 4.x 5.x B C D E F CL-2025/CL-2025-02 ③ represents the decimal part of output voltage VOUT(V) MARK PRODUCT SERIES X.0 X.1 X.2 X.3 X.4 X.5 X.6 X.7 X.8 X.9 0 1 2 3 4 5 6 7 8 9 XCL101**0***-G XCL101**1***-G XCL101**2***-G XCL101**3***-G XCL101**4***-G XCL101**5***-G XCL101**6***-G XCL101**7***-G XCL101**8***-G XCL101**9***-G Example (mark②, ③) XCL101A33***-G ② ③ 3 3 MARK XCL101C28***-G ② ③ C 8 XCL101A50***-G ② ③ 5 0 ④, ⑤ represents production lot number 01～09, 0A～0Z, 11～9Z, A1～A9, AA～AZ, B1～ZZ in order.
