Data Sheet 100mA REGULATED CHARGE PUMP AP3602A/B General Description Features The AP3602A/B are regulated step-up DC/DC Low Quiescent Current: 13 A Typical converters based on charge pump technique. These ICs Regulated Output Voltage Precision: 4% have the ability to supply 100mA constant output High Output Current: current or 250mA peak output current for 100ms from 100mA when V 3.0V IN 3.0V to 5V input (2.7V to 4.5 V for AP3602B), so they 50mA when V 2.7V IN can be used as white LEDs driver or flash LED driver. High Frequency: up to 1.2 MHz Low Shutdown Supply Current: <1 A The AP3602A/B have very low power dissipation and high efficiency in typical applications. Other features High Output Peak Current: 250mA for 100ms include over-temperature protection, low temperature Over Temperature Protection coefficient and etc. to meet some special requirements o o Operating Temperature Range: -40 C to 85 C of hand-held battery powered devices. Applications Only 3 external capacitors are required in applications, which helps to save space and lower cost. These chips Mobile Phone Backlight Driver also have a disable terminal to turn on or turn off the Camera Flash LED Driver chip to ease the use. MP3, MP4 The AP3602A/B are available in SOT-23-6 package. Handheld Device Portable Communication Device SOT-23-6 Figure 1.

Pin Configuration of AP3602A/B (Top View) Pin Description Pin Number Pin Name Function Regulated Output Voltage. V should be bypassed with a 1 F to 22 F low ESR ceramic OUT V 1 OUT capacitor which is placed as close to the pin as possible for best performance Ground. GND should be tied to a ground plane for best performance. The C and C OUT IN 2 GND should be placed as close to this pin as possible Active Low Shutdown Input. A low signal on SHDN disables the AP3602A/B, while a high 3 SHDN signal enables the AP3602A/B. SHDN pin must not be allowed to float Flying Capacitor Negative Terminal. The flying capacitor should be placed as close to this pin 4C- as possible Input Supply Voltage.
