LNK457, LNK454 Single-Stage LED Driver

LNK457 Description

LNK454/456-458/460 LinkSwitch™-PL Family LED Driver IC with TRIAC Dimming, Single-Stage PFC and Constant Current Control for Non-Isolated Applications.

LNK457 Features

* Optimized for non-isolated flyback designs
* Frequency jitter greatly reduces EMI filter size and costs
* Low dissipation direct sensing of LED current Advanced Protection and Safety Features
* Cycle skipping regulation for abnormally low output power to clamp p

LNK457 Applications

* Product Highlights Dramatically Simplifies Off-line LED Drivers
* Flicker-free phase-controlled TRIAC dimming
* Single-stage power factor correction and accurate constant current (CC) output
* Very low component count with small non-electrolytic bulk capacitor for compact
