MAX16927 - Automotive TFT-LCD Power Supply

General Description

The MAX16927 is a highly integrated power supply for automotive TFT-LCD applications.

The device integrates one buck converter, one boost converter, one Cuk converter, two gate-voltage controllers, and two VCOM buffers, one of which supports negative output voltages.

Key Features

  • Operating Voltage Range of 4.5V to 16V (IN3) or 3V to 5.5V (INA).
  • 16V Input, 2A Buck Converter Provides 3.3V Output to TFT Bias-Supply Circuitry and/or Other External Circuitry.
  • Flexible Configuration Allows Single High-Power Positive Output (18V/200mA) or Positive Output (18V, 100mA) and Negative Output (-12V/100mA).
  • One Positive Gate-Voltage Regulator.
  • One Negative Gate-Voltage Controller.
  • DAC-Controlled VCOM Buffers with Offset of 0.
