LNK3792D-H004

High-Efficiency Off-line CV Flyback Switcher IC with Integrated 725 V / 900 V Primary MOSFET, Low No-Load, and Synchronous Rectification

应用

产品详情

The LinkSwitch-XT2SR family dramatically increases the efficiency of auxiliary power supplies used in appliances, consumer products and industrial applications. Ideal for non-isolated designs with a high current, 5 V output, this advanced flyback controller can achieve >90% full load efficiency. High efficiency is maintained over to load range, with >85% efficiency at 100 mW load. No-load consumption is <5 mW.

The default 5 V main output can be adjusted via optional external feedback resistors. Power for start-up and normal operation is supplied from the DRAIN and VOUT pins, eliminating the need for a bias winding and associated

circuitry. The SO-16 package and a low number of external components make the LinkSwitch-XT2SR ICs ideal for compact designs.
