Description

The ISL81401EVAL1Z evaluation board (shown in Figure 5 on page 8) features the ISL81401, a 40V high voltagesynchronous buck-boost controller that offers external soft-start, independent enable functions and integratesUV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 600kHz helps to optimizeinductor size while the strong gate driver delivers up to 20A for the buck-boost output.

Characteristics

  • Wide input range: 6V to 40V
  • Bi-directional operation
  • High light-load efficiency in pulse skipping DEM operation
  • Programmable soft-start
  • Optional DEM/PWM operation
  • Optional CC/HICCUP OCP protection
  • Supports prebias output with soft-start
  • PGOOD indicator
  • OVP, OTP, and UVP protection
  • Back biased from output to improve efficiency
