TPS65131TRGERQ1

The Texas Instruments TPS65131TRGERQ1 is an active automotive split-rail DC-DC converter. It is designed to provide dual, positive and negative outputs, making it suitable for applications such as LCD and OLED display power and drivers. The device accepts an input voltage range of 2.7V to 5.5V and can generate output voltages up to 15V and down to -15V.

Key features include a typical switch current limit of 2A for boost and inverter main switches, high conversion efficiency up to 91% at the positive output rail and up to 85% at the negative output rail. It operates at a minimum fixed frequency of 1.25MHz (1.38MHz typical) and includes power-save mode at low load. The device also offers independent enable inputs for power-up and power-down sequencing, thermal shutdown, and overvoltage protection on both outputs.

Packaged in a compact 4mm x 4mm VQFN-24 package (RGE) with wettable flanks, the TPS65131TRGERQ1 is qualified for automotive applications and meets AEC-Q100 test guidance. Its operating temperature range is -40°C to 105°C (ambient).

This converter is ideal for applications requiring bipolar IC integration for LCD bias, suitable for displays ranging from 7 inches to 13 inches. The adjustable sequencing and control output for external PFET support complete supply disconnect when shut down.
