HV9910B Datasheet (Microchip) - Universal High-Brightness LED Driver

HV9910B, Universal High-Brightness LED Driver

HV9910B is an open loop, current mode control, LED driver IC.

This IC 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 vol
