UNIVERSAL HIGH BRIGHTNESS LED DRIVER

DESCRIPTION

FEATURES

The A9910 is a PWM high-efficiency LED driver

control IC. It allows efficient operation of

high-brightness (HB) LEDs from voltage sources

ranging from 10VDC up to 600VDC. The A9910

controls an external MOSFET at fixed switching

frequencies up to 300kHz. The frequency can be

programmed using a single resistor. The LED string

is driven at a constant current rather than a constant

voltage, thus providing a constant light output and an

enhanced reliability. The output current can be

programmed between a few milliamps and up to

more than 1.0A. The A9910 uses a rugged

high-voltage junction isolated process that can

withstand an input voltage surge up to 600V. The

output current to a LED string can be programmed to

any value between zero and its maximum value by

applying an external control voltage at the linear

dimming control input of the A9910. The A9910

provides a low-frequency 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.

The A9910 is available in SOP8 package.
