Charge Pump type DC/DC Converter for White LED Driver

■Application

Charge Pump type DC/DC Converter / White LED Driver

■Features

TCA62751FTG is a charge pump type DC-DC converter,

and outputs LED current 480mA or more to 3.2-4.2V input.

■Function

1, 1.5 or 2 times Charge Pump type step up DC-DC converter

Two modes can be selected for the setting of step up time

Automatic change mode

(VIN/IOUT is observed, and an automatic change of step up time.)

Step up time fixation mode

■Features

● Fabricating with CMOS Process
