Номер в каталоге : HV9910B
Function : Universal High Brightness LED Driver
Производитель : Unspecified
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.
