HV9910B

Universal High-Brightness LED Driver

Features

Description

• Switch mode controller for single switch LED drivers

• Enhanced drop-in replacement to the HV9910

• Open loop peak current controller

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 voltage supply. 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 lin-

ear dimming of the LED current.

• Internal 8.0 to 450V linear regulator

• Constant frequency or constant off-time operation

• Linear and PWM dimming capability

• Requires few external components for operation

Applications

• DC/DC or AC/DC LED driver applications

• RGB backlighting LED driver

• Back lighting of flat panel displays

• General purpose constant current source

• Signage and decorative LED lighting

• Chargers

HV9910B is ideally suited for buck LED drivers. Since

the HV9910B operates in open loop current mode con-

trol, the controller achieves good output current regula-

tion without the need for any loop compensation. PWM

dimming response is limited only by the rate of rise and

fall of the inductor current, enabling very fast rise and

fall times. HV9910B requires only three external com-

ponents, apart from the power stage, to produce a con-

trolled LED current. This makes HV9910B an ideal

solution for low cost LED drivers.
