TPS65166 具有反向降压/升压和温度 补偿的 5 通道 LCD 偏置(4.2A 最低 升压 Ilim.,2.6A 最低 降压 Ilim)

TPS65166 描述

The TPS65166 offers a compact power supply solution to provide all voltages required by a LCD panel for large TV panel applications running from a 12V supply rail. The device is optimized to support LCD technology using ASG gate drive circuits. The device generates all voltage rails for the TFT LCD bias (VS, VONE, VOFFE, VSS). In addition to that it includes a step-down converter (Vlogic) to provide the logic voltage. By pulling the HVS pin high an implemented high voltage stress test feature programs the boost converter output voltage Vs to higher values. The boost converter operates at a fixed switching frequency of 750kHz. The positive charge pump is running from the boost converter and is regulated by an external transistor.
