Package: VQFN (24) Type

Manufacturer: Texas Instruments


TPS65131-Q1 datasheet



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.

Application Schematic :



1. Independent Enable Inputs for Power-Up and Power-Down Sequencing

2. Control Output for External PFET to Support Complete Supply Disconnect When Shut Down

3. 2.7-V to 5.5-V Input-Voltage Range

4. Minimum 1.25-MHz Fixed-Frequency PWM Operation

5. Thermal Shutdown

6. Overvoltage Protection on Both Outputs
