The TPS65160 is a bias power supply solution for TV and monitor TFT LCD panels. It features internal and adjustable soft start, output voltage range up to 20V, short-circuit protection, 1% accurate 2.8A boost converter, and 1.5% accurate 1.8A step-down converter, among other characteristics.
The TPS65160 and TPS65160A are compact bias power supply solutions that generate all four voltages required by thin‑film transistor (TFT) LCD panels. The devices combine a boost converter for the source voltage and a step‑down converter for the logic voltage, with integrated charge‑pump drivers for VGL and VGH.
Key features include an 8‑V to 14‑V input range, selectable 500 kHz or 750 kHz switching frequency, over‑voltage and short‑circuit protection, thermal shutdown, and a TSSOP‑28 package that can be supplied taped‑and‑reeled. Typical applications are large‑screen monitor panels and LCD TV modules.
