DESCRIPTION
UL96A 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.
UL96A 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.
UL96A 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.
UL96A has a variety of protection features, including LED short
circuit protection, under voltage protection, over temperature
adjustment function and so on.
