Overview

UNISONIC TECHNOLOGIES CO.
, LTD UL82C Preliminary NON ISOLATED BUCK CONSTANT CURRENT LED DRIVER IC  DESCRIPTION UL82C is a high precision LED BUCK constant current driver chip.
The chip operates in the inductor current critical continuous mode, which is suitable for the non isolated buck LED constant current power supply with 85Vac~265Vac full range input voltage.
UL82C chip integrated 500V power switch by patent demagnetization detection technology and high voltage power supply technology, without detection and power supply for auxiliary winding, the peripheral devices are more simple, saving the cost and volume of the system.
UL82C chip with high precision current sampling circuit, whil...
