TPS7H4001-SP Datasheet 18-a Synchronous Buck Converter

Manufacturer: Texas Instruments

Overview: TPS7H4001-SP SLVSEN7D – APRIL 2019 – REVISED MAY 2023 TPS7H4001-SP Radiation-Hardness-Assured 3-V to 7-V Input 18-A Synchronous Buck Converter.

General Description

The TPS7H4001-SP is a radiation-hardness-assured, 7-V, 18-A synchronous buck converter with integrated low-resistance high-side and low-side MOSFETs.

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:.
  • Radiation-hardness-assured up to TID 100 krad(Si).
  • SEL, SEB, and SEGR immune to LET = 75 MeV-cm2/mg.
  • SET and SEFI characterized up to LET = 75 MeV-cm2/mg.
  • Peak efficiency: 95.5% (VO = 1 V at 100 kHz).
  • 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-kHz to 1-MHz.
  • SYNC pins can be conf.
