The Texas Instruments TPS65170 is a specialized integrated circuit designed for LCD bias applications, commonly found in LCD TVs and monitors. This IC provides a power supply solution with an input voltage range from 8.6V to 14.7V.
Key electrical characteristics include a boost converter with a switch current limit of 2.8A and output voltages up to 18.5V, and a buck converter with a switch current limit of 1.5A. Both converters operate at a fixed 750kHz switching frequency. The device supports source driver voltages from 13V to 18.5V.
Environmental specifications indicate an operating temperature range of -40°C to 85°C. The TPS65170 is housed in a 28-pin VQFN (RHD) package with an area of 25 mm² (5 mm × 5 mm).
Additional features include short-circuit protection for both boost and buck converters, fixed buck converter soft-start, programmable boost converter soft-start, two charge pump controllers for VGH and VGL regulation, a control signal for an external high-side MOSFET, an isolation switch, a reset signal with programmable pulse duration, and thermal shutdown.
The input voltage range is 8.6 V to 14.7 V.
The maximum source driver voltage is 18.5 V.
The operating temperature range is -40°C to 85°C.
The TPS65170 is available in a 28-pin VQFN (RHD) package.
The switching frequency for both the buck and boost converters is fixed at 750 kHz.
