TPS92002 Overview
The TPS92001/2 family of general LED lighting PWM controllers contains control and drive circuitry required for off-line isolated or non-isolated LED lighting applications. The controllers can support Phase Cut TRIAC dimming with minimal external ponents. The controllers can also be implemented for stage conversion where the power factor (PF) exceeds regulatory requirements for lighting.
