TPS65165EVM-233
The TPS65165EVM-233 takes a 2.5-V to 6-V input rail and provides the three
bias-supply voltages and three integrated opamps that are required for TV and monitor
TFT-LCD panels. The TPS65165EVM-233 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. External passive components to support
the boost converter include inductors and capacitors, and external components for the
charge pumps include capacitors.
