TPS65130 (ACTIVE) Split-Rail Converter with Dual, Positive and Negative Outputs (300mA typ)

 

Recommended alternative parts

  • TPS65132  -  Single inductor dual output regulator, supports +/-4.0...6.0V, up to 80mA load
  • TPS65133  -  Dual output regulators, fixed at +/-5.0V, supports loads up to 250mA

Description

The TPS6513x 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 in a 200-mA range in typical applications, 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 the devices to be powered from batteries or from fixed 3.3-V or 5-V supplies. The TPS6513x comes in a small 4-mm × 4- mm VQFN-24 package. Together with a minimum switching frequency of 1.25 MHz, the device enables designing small power supply applications because it requires only a few small external components.

The converter operates with a fixed frequency PWM control topology and, if power-save mode is enabled, it uses a pulse-skipping mode at light-load currents. It operates with only 500-µA device quiescent current. Independent enable pins allow power-up and powerdown sequencing for both outputs. The device has an internal current limit overvoltage protection and a thermal shutdown for highest reliability under fault conditions.
