TPS7H4003-SEP Datasheet 18-a Synchronous Buck Converter

Manufacturer: Texas Instruments

Overview: TPS7H4003-SEP SLVSG41 – JANUARY 2022 TPS7H4003-SEP Radiation-Tolerant 3-V to 7-V Input 18-A Synchronous Buck Converter in Space Enhanced Plastic.

General Description

The TPS7H4003-SEP is a radiation-tolerant, 7-V, 18A synchronous buck converter with integrated lowresistance high-side and low-side MOSFETs in a thermally enhanced 34-pin ceramic flatpack package.

High efficiency and reduced ponent count are achieved through current mode control.

The output voltage start-up ramp is controlled by the SS/TR pin which allows operation as either a stand alone power supply or in tracking situations.

Key Features

  • Radiation performance:.
  • SEL, SEB, and SEGR immune up to LET = 43 MeV-cm2/mg.
  • SET and SEFI characterized up to LET = 43 MeV-cm2/mg.
  • TID assured for every wafer lot up to 50 krad(Si).
  • Peak efficiency: 94% (VO = 1 V at 100 kHz).
  • Integrated 17-mΩ and 9-mΩ MOSFETs.
  • Power rail: 3 V to 7 V on VIN.
  • Flexible switching frequency options:.
  • 100-kHz to 1-MHz adjustable internal oscillator.
  • External sync capability: 100.
