Product Overview

38V, 5W synchronous ISO-buck converter evaluation board with dual isolated output based on the L6986I. The primary output voltage can be accurately adjusted, whereas the isolated secondary output is generated by using a transformer. No optocoupler is required. The STEVAL-L6986IV1 evaluation board generates two isolated voltages (positive around 18 V and negative between 4 and 5 V), particularly suitable for supplying the IGBT/SiC MOSFET gate driver for multiple applications. A simple by-pass enables the supply of a single isolated voltage.
  • Designed for iso-buck topology
  • 4 to 38V operating input voltage
  • Primary output voltage regulation/no optocoupler required
  • 1.9A typical sink peak primary current capability
  • Peak current mode architecture in forced PWM operation
  • 300ns blanking time, adjustable fSW and synchronization and adjustable soft-start time
  • Embedded primary output voltage supervisor
  • Internal primary current limiting, overvoltage protection
  • Thermal shutdown
