100mA REGULATED CHARGE PUMP AP3602A/B

Dec. 2012 Rev. 2. 0 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.
