

DESCRIPTION

UL82B 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.

UL82B 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.

HSOP-8

SOT-89

UL82B chip with high precision current sampling circuit, while

the use of patented constant current control technology to achieve

high accuracy of the LED constant current output and excellent line

voltage regulator. The chip operates in the critical mode of inductor

current and the output current is not changed with the increase of

the inductance and the working voltage of LED.

TO-92

UL82B has a variety of protection features, including LED short

circuit protection, under voltage protection, over temperature

adjustment function and so on.



FEATURES

* The integrated 500V power mos.
