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.
