1 / 17 page  100mA REGULATED CHARGE PUMP AP3602A/B 1 Apr. 2007 Rev. 1.2 BCD Semiconductor Manufacturing Limited Data Sheet General Description The AP3602A/B are regulated step-up DC/DC converters based on charge pump technique. These ICs have the ability to supply 100mA constant output current or 250mA peak output current for 100ms from 3.0V to 5V input (2.7V to 4.5 V for AP3602B), so they can be used as white LEDs driver or flash LED driver. The AP3602A/B have very low power dissipation and high efficiency in typical applications. Other features include over-temperature protection, low temperature coefficient and etc. to meet some special requirements of hand-held battery powered devices. Only 3 external capacitors are required in applications, which helps to save space and lower cost. These chips also have a disable terminal to turn on or turn off the chip to ease the use. The AP3602A/B are available in SOT-23-6 package. Features · Low Quiescent Current: 13µA Typical · Regulated Output Voltage Precision: 4% · High Output Current: 100mA when VIN≥3.0V 50mA when VIN≥2.7V · High Frequency: up to 1.2 MHz · Low Shutdown Supply Current: <1µA · High Output Peak Current: 250mA for 100ms · Over Temperature Protection · Operating Temperature Range: -40oC to 85oC Applications · Mobile Phone Backlight Driver · Camera Flash LED Driver · MP3, MP4 · Handheld Device · Portable Communication Device Figure 1.
