HIGH POWER FACTOR LINEAR

CONSTANT CURRENT LED

DRIVER



DESCRIPTION

UTC UL52B is a high power factor linear constant current LED

HSOP-8

driver which is applied to LED lighting. Through the distinctive

constant current control technology, it realizes that constant current

accuracy is less than ±5% and output current is adjustable through

external resistor. High power factor and low harmonic distortion are

the particular features.

The system is simple without transformer and electrolysis

capacitor. Therefore, LED lighting batch job can be realized.



FEATURES

* No transformer and high voltage electrolysis capacitor

* Integrated high voltage startup power supply circuit

* Adjustable output current, max 60mA

* Inter-chip current deviation = 5%

* Efficiency: >90%

* Power factor: >0.95

* THD<20%

* Over temperature protection

* Application system no EMI problems
