TJ9910 Datasheet (HTC) - Universal High Brightness LED Driver

TJ9910, Universal High Brightness LED Driver

The TJ9910 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.

TJ9910 controls an external MOSFET at fixed switching frequencies up to 300 kHz.

The frequency can be programmed using a single
