Beschreibung

The ISL81401AEVAL1Z evaluation board (shown in Figure 4 on page 8) features the ISL81401A, 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 optimizethe inductor size while the strong gate driver delivers up to 20A for the buck-boost output.

Eigenschaften

  • Wide input range: 6V to 40V
  • 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

Typische Anwendungen

  • Aftermarket automotive
  • Battery powered industrial applications / Robot and drones / Security surveillance
  • Battery backup
  • Medical equipment
  • Type-C power supply and chargers / Redundant power supplies
