This product has been released to the market and is available for purchase. For some products, newer alternatives may be available.
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


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.


  • 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
  • ±1% Output Voltage Accuracy
  • High Efficiency
  • 250-mA Output Current Capability
