Diodes Incorporated AP5727

BIAS POWER SUPPLY FOR OLED SUB DISPLAY AND TFT-LED

Overview

TopologyBoost Converter
Input voltage2.7-5.5 V
Switching frequency1000-1400 kHz
Output 130 V
IC revision2-2

Description

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).

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.

Features

  • 30V High Output Voltage
  • Fast 1.2MHz Switching Frequency
  • Current limit and UVLO Protections
  • Internal Thermal Shutdown
  • Maximum 1μA Shutdown Current
  • Integrated Soft-start Function
  • SOT25: Available in “Green” Molding Compound(No Br, Sb)
  • Lead Free Finish/RoHS Compliant (Note 1)

Remarks:

  • A 10μH~22μH inductor is recommended for most AP5727 applications

Typical applications

  • OLED bias supply for a clamshell handset sub display
  • Small size TFT-LCD Bias power supply.
  • RF amplifier bias voltages
