TPS7H4001-SP - 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 component count are achieved through current mode control.

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.
