Description

he ISL81805EVAL4Z dual-phase negative-topositive voltage conversion evaluation board (shown in Figure 4) features the ISL81805: an 80V high voltage, dual synchronous boost controller that offers external soft-start and independent enable functions and integrates UV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 1MHz helps optimize the inductor size as the strong gate driver delivers up to 20A for the total 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

  • Telecommunications, Servers and data centers
  • Industrial equipment
  • Automotive electronics
  • Power systems
