Short description

The IL9910 is a high efficient LED driver specifically designed for driving multi-LED

strings or arrays, supplied from either universal AC line or any DC voltage range 8 -

450V. IC drives external MOSFET-gate with fixed frequency up to 300kHz. The operating

frequency can be set using an external resistor. LED strings is controlled by DC voltage

that ensures stable brightness and extends their lifetime.. LED string output current can be

set from a few mA to more than 1A by external voltage applied to Linear Dimming (LD) in-

put. The IL9910 feature is PWM_D pin that allows PWM control of brightness with duty

cycle from 0 to 100 % and frequency up to few kHz.

Application information

The IL9910 is a high efficient LED driver, used in boost or buck-boost converter

circuits, specifically designed for driving multi-LED strings or arrays.

It can be operated from either universal AC line or any DC voltage between 8-450V.

When the input power to the light equipment does not exceed 25W, a power factor cor-

rection circuit can be used to filter AC pulsations. The IL9910 can drive up to hundreds of

High-Brightness (HB) LEDs or multiple strings of HB LEDs. The LED arrays can be config-

ured as a series or series/parallel connection.
