TPS65133 Split-Rail Converter, ±5V, 250mA Dual Output Power Supply | TI.com

TPS65133 (ACTIVE) Split-Rail Converter, ±5V, 250mA Dual Output Power Supply

 

Recommended alternative parts

  • TPS65132  -  +/-4...6V but at 80mA (compared to fixed @ +/-5.0V at 250mA)
  • TPS65130  -  up to +/-15V instead of fixed @+/-5.0V

Description

The TPS65133 is designed to supply any system requiring ±5.0-V supply rails. Each output can supply up to 250 mA of output current. The input supply voltage range is suitable for use with lithium ion batteries or from a fixed 3.3-V supply.

Efficiency is typically over 90% for most applications (operating from a lithium ion battery, output currents in the range 50 mA to 200 mA). The two converters in the TPS65133 device operate independently, allowing 100% mismatch between positive and negative output currents.

Features

  • 2.9-V to 5.0-V Input Voltage Range
  • Fixed 5.0-V Positive Output Voltage (VPOS)
  • Fixed –5.0-V Negative Output Voltage
    (VNEG)
