LNK353 - (LNK353 / LNK354) Low Power Off-Line Switcher IC

Description

source, frequency jittering, cycle-by-cycle current limit, and thermal shutdown circuitry onto a monolithic IC.

Features

• Optimized for Lowest System Cost.
• Fully integrated auto-restart for short-circuit and open loop protection.
• Self-biased supply.
• saves transformer auxiliary winding and associated bias supply components.
• Tight tolerances and negligible temperature variation on key parameters eases design and lowers cost.
• High maximum switching frequency allows very low flux density transformer designs, practically eliminating audible noise.
• Frequency jittering.
