The HV9910C is designed to convert high voltage supplies (85 V – 265 VAC rectified) or (15 V – 450 VDC) to a constant current source for powering a string or a combination of strings of high brightness LEDs.
The device can be programmed to operate in either a constant frequency or constant off-time mode and includes a 15 – 450V linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply. The additional package option (8L SOIC with Heat Slug) allows for improved thermal properties.
