IRS27952S - RESONANT HALF-BRIDGE CONVERTER CONTROLLER

Download the IRS27952S datasheet PDF. This datasheet also covers the IRS27951S variant, as both devices belong to the same resonant half-bridge converter controller family and are provided as variant models within a single manufacturer datasheet.

Description

The IRS2795(1,2)(4) is a self oscillating half-bridge driver IC for DC-DC resonant converter applications, especially the LLC resonant half-bridge converter.

The frequency and dead time can be programmed externally using two external components.

Features

  • Simple primary-side control solution for fixed and variable frequency DC-DC resonant converters.
  • Max 500kHz per channel output with 50% duty cycle.
  • Floating channel bootstrap operation up to +600Vdc.
  • Programmable minimum and maximum switching frequency.
  • Programmable soft start frequency and soft start time.
  • Programmable dead time.
  • Micropower start-up & ultra low quiescent current.
  • Over-current protection using low side MOSFET Rds(on).
  • User initiated.
