Features

General Description

► Switch mode controller for single switch LED

The HV9910C is an open loop, current mode, control LED driver

IC. The HV9910C can be programmed to operate in either a

constant frequency or constant off-time mode. It 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. HV9910C includes a TTL compatible 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. As opposed to

the HV9910B, the HV9910C is equipped with built-in thermal-

shutdown protection.

drivers

► Enhanced drop-in replacement to the HV9910B

► Open loop peak current controller

► Internal 15 to 450V linear regulator

► Constant frequency or constant off-time operation

► Linear and PWM dimming capability

► Requires few external components for operation

► Over-temperature protection

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

The HV9910C is ideally suited for buck LED drivers. Since

the HV9910C operates in open loop current mode control, the

controller achieves good output current regulation without the

need for any loop compensation. Also, being an open loop

controller, PWM dimming response is limited only by the rate

of rise of the inductor current, enabling a very fast rise and fall

times of the LED current. The HV9910C requires only three

external components (apart from the power stage) to produce

a controlled LED current making it an ideal solution for low cost

LED drivers.
