XC9306B05G0R-G ETR06003-003 Synchronous Rectification Buck-Boost DC/DC Converter IC ☆GreenOperation Compatible ■GENERAL DESCRIPTION The XC9306B05G0R-G is a synchronous buck-boost DC/DC converter IC with built-in FETs. The circuit topology switches over between buck and boost smoothly based on the relationship of the input voltage and the output voltage which is observed by the internal PWM controller. Due to the internal FETs, the number of external components is reduced. Also, a 6MHz switching frequency enables smaller external components, such as a coil and capacitors, to be used. The input voltage range is 2.5V~5.5V and the output voltage is adjustable from 0.8V to 5.0V by using external resistors since the reference voltage circuit is embedded internally. Synchronous topology provides high efficiency performance and the control method is selectable from either PWM mode (MODE pin: H) or PFM mode (MODE pin: L). Under PFM mode, the efficiency at light load current will be improved. When a “L” signal level is fed to the CE pin, the product is in stand-by mode and the consumption current is going to be 2.0uA (Max.) or less. Regarding other functions, the product has UVLO, thermal shutdown protection and soft-start. The soft-start time is approx. 100us and the output voltage can rise up quickly. ■FEATURES ■APPLICATIONS Input Voltage Range Output Voltage Setting Range Oscillation Frequency Efficiency Control Methods Protection Circuit ● RF Power Amplifiers ● Mobile Phones, Smart Phones ● Portable Information Devices ● MP3 Players ● Digital Still Cameras ● Products powered by Li-ion 1 cell batteries Function Output Capacitor Coil Value Package Environmentally Friendly : 2.5V～5.5V : 0.8V～5.0V (FB=0.5V) : 6.0MHz : 92%(VIN=4.2V, VOUT=3.3V/300mA) : PWM (Mode=High, ILIM=Low) : Current Limit Thermal Shutdown : Soft-start Power Save (Mode=Low) UVLO : Ceramic Capacitor Compatible : 0.5 (0.47) μH : WLP-20-01 : EU RoHS Compliant, Pb Free ■TYPICAL APPLICATION CIRCUIT ■ TYPICAL PERFORMANCE CHARACTERISTICS XC9306B05G0R-G Vout=3.3V L1 100 PFM Lx2 80 ILIM MODE VIN VOUT VIN VOUT R1 CIN1 CL FB VDD CIN2 R3 VSEL_SW CE PGND VSEL AGND R2 Efficiency : EFFI [%] Lx1 60 VIN=2.5V 40 4.2V 20 PWM 0 0.1 1 10 100 Output Current : IOUT [mA] 1000 1/14 XC9306B05G0R-G is Discontinued.

XC9306B05G0R-G ■OPERATIONAL DESCRIPTION This IC consists of a reference voltage (Vref), error amplifier, phase compensation circuit, MOSFET (SW1 to SW5), oscillator circuit, UVLO circuit, gate control circuit, current limiting circuit, and other components. An internal PWM controller monitors the input/output voltage, and operation takes place in either step-up or step-down mode. The states of the MOSFET (SW1 to SW5) during operation are shown below. SW1 SW2 SW3 SW4 Step-Up Fixed at ON Fixed at OFF Switching Switching Switching Step-Down Switching Switching Fixed at OFF Fixed at ON Fixed at ON Lx2 Lx1 SW1 VIN SW5 SW5 SW2 SW3 VOUT SW4 Current Sensor VDD VSEL Gate Control VSEL_SW Error Amp. CE Oscillator AGND MODE Device Control Thermal Shutdown Vref UVLO ILIM PGND FB This is the reference voltage that keeps the output voltage of the IC stable. The internal oscillator output a 5.8MHz (TYP.) clock signal to set a switching frequency. The error amp monitors the output voltage.The voltage divided by the internal R1 and R2 resistors is a feedback voltage for Error Amp. and compared to the reference voltage. The output voltage of the error amp becomes higher when the feedback voltage is higher than the reference voltage. To prevent unstable operation of the internal circuitry when the input voltage drops below 1.9V (TYP.), this function forcibly stops operation. When the input voltage rises above 2.0V (TYP.), switching operation takes place. Controls ON/OFF of the MOSFET of SW1 to SW5. XC9306B05G0R-G has the soft-start function to prevent rush current upon turning on of the power. The startup time is approximately 0.1ms. The over temperature protection circuit is built-in as a protection circuit. When junction temperature reaches +135°C, the over temperature protection circuit turns off MOSFET. Also, when the junction temperature falls to +110°C, this IC operates normally. The over current protection circuit detects peak value (ILpeak) of the inductor current flowing through the inductor from the internal MOSFET (SW1). To improve efficiency when the load is light, the IC has PFM mode. This mode is enabled by setting the MODE pin to "Low" voltage. When in PFM mode, the mode will automatically change to PWM mode if the load current increases. The maximum output current of PFM mode is lower than PWM mode. 8/14 XC9306B05G0R-G is Discontinued. XC9306B05G0R-G ■NOTE ON USE 1) For the phenomenon of temporal and transitional voltage decrease or voltage increase, the IC may be damaged or deteriorated if IC is used beyond the absolute MAX. specifications. 2) The operation may become unstable due to noise and/or phase lag from the output current when the wire impedance is high. 3) 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. 4) Instructions of pattern layouts Please place the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. Route a large current flows, please wiring short in the surface layer. The pattern on which the IC is mounted should be sufficiently large to allow the IC to dissipate heat. 5) NOTES ON MOUNTING In general, the underfill material and sealing method affect the reliability of mounting. Spansion does not evaluate the mounting using the underfill material. It is advisable for each customer to evaluate the mounting enough. 6) Handling cautions The structure of the wafer-level CSP (WLP) is such that the silicon chip is exposed at the back and on the side of the package. Silicon is a hard and brittle substance. When handling, take care that the silicon is not subjected to mechanical shock. Silicon is also a conductor, and thus this should be taken into consideration when developing the design. 6)-1 Do not use metal tweezers or other sharp tool or jig to handle the product. Use a tool such as suction-type tweezers with plastic or soft rubber tips. 6)-2 Take care that the silicon parts are not subjected to mechanical shock after mounting on the board. 9/14 XC9306B05G0R-G XC9306B05G0R-G is Discontinued. ■TYPICAL PERFORMANCE CHARACTERISTICS (1) Efficiency vs. Output Current VOUT=3.3V, PWM Mode VOUT=3.3V, PFM Mode (Power Save) (2) Output Voltage vs. Output Current VOUT=3.3V, PWM Mode VOUT=3.3V, PFM Mode (Power Save) (3) Ripple Voltage vs. Output Current VOUT=3.3V, PWM Mode 10/14 VOUT=3.3V, PFM Mode (Power Save) XC9306B05G0R-G is Discontinued.
