TPS65162EVM-278
The TPS65162EVM-278 evaluation module operates from a 8-V to 14-V input rail and provides the three
bias-supply voltages (Vs, VGH, and VGL) and a logic-supply voltage (3.3 V) that are required for television
and monitor TFT-LCD panels. This device also provides two operational amplifiers to generate the VCOM
supply rail. The TPS65162EVM-278 has one boost converter with an integrated low-side FET, one
negative charge-pump controller requiring external Schottky diodes, and one fully integrated positive
charge pump for TFT-LCD bias supply. External passive components to support the boost converter
include rectifying diode, inductors, and capacitors. External components for the charge pumps include
capacitors and switching diodes. One nonsynchronous buck converter with external Schottky diode make
up the logic supply.
