AP5727

BIAS POWER SUPPLY FOR OLED

SUB DISPLAY AND TFT-LED

Description

Pin Assignments

The AP5727 is a high efficiency boost converter in a

compact SOT25 that provides the bias voltages for OLED

Sub Display and TFT-LCD (Liquid Crystal Display).

high 1.2MHz switching frequency and internal

compensation minimizes external part count, PCB area and

cost. Integrated soft start reduces inrush current.

The AP5727 has a 1.25V feedback voltage making it

compatible with industry standard boost converters used to

bias LCD panels.
