Version: A14

SOT-26

Description

TS19310 is a buck/boost control IC with phase angle decoding circuit and hold current adjusting function for

TRIAC dimming LED lighting. TS19310 achieves high power factor and low total harmonic distortion (THD)

operation by boundary conduction mode (BCM). The line and load regulation of LED current is about ±3%, based

on particular control method.
