Part Number: TPS65131-Q1

Function: Automotive Catalog Dual Positive and Negative Outputs (1800mA)

Package: VQFN (24) Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The TPS65131-Q1 device is dual-output dc-dc converter generating a positive output voltage up to 15 V and a negative output voltage down to –15 V with output currents of typically 200 mA, depending on input-voltage to output-voltage ratio.

With a total efficiency up to 85%, the device is ideal for portable battery-powered equipment. The input-voltage range of 2.7 V to 5.5 V allows, for example, 3.3-V and 5-V rails to power the device. The device comes in a QFN-24 package with thermal pad. Requiring few and small external components, the overall solution size can be small.
