HV9910B datasheet

Описание :

The  HV9910B  is  an  open  loop,  current  mode,  control  LED driver  IC. The  HV9910B  can  be  programmed  to  operate  in either  a  constant  frequency  or  constant  off-time  mode. 

It includes an 8.0 — 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 HV9910B includes a PWM dimming input that can accept an external control signal with a duty ratio of 0 — 100% and a frequency of up to a few kilohertz. It also includes a 0 — 250mV linear dimming input which can be used for linear dimming of the LED current.
