Description

This reference guide describes the specifications, usage, and efficiency properties of 1 kW full-bridge DC-DC converter (this power supply). This power supply is capable of supplying 1 kW power at the DC 54 V output. The input-voltage range is from DC -36 V to -60 V, and it can be used in applications including communication-related equipment, industrial equipment, and various other applications. This reference guide provides various design information including reference design, and contributes to reduction of effort required in designing according to actual specifications.

Features

  • High-speed switching
  • Small gate charge: QSW = 28 nC (typ.)
  • Small output charge: Qoss = 90 nC (typ.)
  • Low drain-source on-resistance: RDS(ON) = 1.9 mΩ (typ.) (VGS = 10 V)
  • Low leakage current: IDSS = 10 µA (max) (VDS = 80 V)
  • Enhancement mode: Vth = 2.5 to 3.5 V (VDS = 10 V, ID = 1.0 mA)

Typical applications

  • High-Efficiency DC-DC Converters, Switching Voltage Regulators, Motor Drivers
