Product details

Secondary-side synchronous rectifier driver with military temperature range

The LT8311MPFE#PBF is a secondary-side synchronous MOSFET controller from Analog Devices, designed to drive N-channel MOSFETs in the secondary of isolated forward or flyback converters.

Package and thermal path — exposed pad is mandatory

The LT8311MPFE#PBF is supplied in a 20-lead TSSOP with an exposed pad (20-TSSOP-EP), surface-mount. Shipping form is Tube — not Tape & Reel. If your pick-and-place line is set up for reel feed, factor in the tube-to-reel transfer or specify the reel-packaged variant if one exists on the same die.

Frequently asked questions

What is the typical application for the LT8311MPFE#PBF?

The LT8311MPFE#PBF is a secondary-side controller for synchronous rectification in isolated DC-DC converters. Typical applications include telecom power modules, industrial brick converters, avionics power supplies, and satellite bus converters where the secondary-side ambient temperature can reach 150°C.
