Description
The AP5727 is a high efficiency boost converter in a compact SOT25 that provides the bias voltages for O°C Sub Display and TFT-LCD (Liquid Crystal Display). A 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.
Application
- Small size TFT-LCD Bias power supply.
- OLED bias supply for a clamshell handset sub display.
- RF amplifier bias voltages
