HB LED driver

24 July 2013 Opto-Electronics

The HV9910C is an open loop, current mode, universal high brightness (HB) LED driver IC from Supertex. It is ideal for general and decorative LED lighting, flat panel display backlighting, and other DC/DC or AC/DC input based applications. The device is designed to convert high voltage supplies (85 V–265 V a.c. rectified or 15 V–450 V d.c.) to a constant current source for powering a string or a combination of strings of HB LEDs. It can be programmed to operate in either a constant frequency or constant off-time mode and includes a 15–450 V linear regulator which allows it to work from a wide range of input voltages without the need for an external low-voltage supply.
