These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
The TPS65162 generates all four voltage rails for a TFT LCD (Vs, Vlogic, VGH and VGL) and includes two
op-amps to generate the VCOM supply rail. An input-to-output isolation switch is integrated into the device,
providing short-circuit protection for the boost converter. A current-limit function is implemented in the
input-to-output isolation switch to allow soft turn-on during start-up. The device also features gate voltage
shaping for improved TFT-LCD picture quality. The device consists of a boost converter to provide the source
voltage Vs, and a step-down converter to provide the logic voltage for the system. A positive and a negative
charge-pump driver provide adjustable regulated output voltages VGH and VGL to bias the TFT. Both boost and
buck converter, as well as the charge-pump drivers, operate with a fixed switching frequency of 500 kHz or 750
kHz, selectable by the FREQ pin. The device includes adjustable power-on sequencing. The safety features of
the device are overvoltage protection for boost converter, short-circuit protection for Vs, Vlogic and VGH, and
thermal shutdown.
