IRS27951S Product details

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.
