PMP30473 Reference Design

Texas Instruments

Lowest noise auxiliary dual output power supply reference design


This reference design is a 2 x 1-W inverting buck boost converter. The two output voltages (+5 V and -5 V) are produced from one single buck silicon (TPS57160-Q1). Post regulators (and post filters) ensure ripple free output voltages. Input voltage range covers automotive and industrial applications. 

  • Input filter ensures lowest reflected ripplePower stage withstands surge voltages up to 42 VCircuit tolerates cranking down to 4 VTemperature rise is less than 20 K at full load and with nominal automotive input voltage
  • On-board (OBC) & wireless charger
