Description

The IRS29831 includes an internal 700V rated MOSFET with low RDSon to enable driver operation up to 25W with minimal temperature rise. A snubber network consisting of DSNUB, CSNUB and RSNUB is required in Flyback converters to limit the peak ringing transient. In a typical circuit with appropriate snubber values the transient will not exceed 650V at maximum line input.
