Output 25 V / 20 A
IC revision1.00

Description

The ISL81805EVAL3Z dual-output evaluation board,with negative-to-positive voltage conversion (shown in Figure 4) features the ISL81805, which is an 80Vhigh voltage, dual synchronous boost controller that offers external soft-start and independent enable functions and integrates UV/OV/OC/OT protection. Aprogrammable switching frequency ranging from 100kHz to 1MHz helps optimize the inductor size as the strong gate driver delivers up to 20A for each output.

Features

  • Negative-to-positive voltage conversion
  • Wide input range: -36V to -60V
  • Programmable soft-start
  • Optional DEM/PWM operation
  • Optional input/output constant current OCPprotection
  • Supports pre-bias output with soft-start
  • PGOOD indicator
  • OVP, OTP, and UVP protection

Typical applications

  • Automotive electronics
  • Power system
  • Telecommunication, Server and data center
  • Industrial equipment
