TJ9910A Datasheet (HTC) - Universal High Brightness LED Driver

TJ9910A, Universal High Brightness LED Driver

The TJ9910A is a PWM high-efficiency LED driver control IC.

It allows efficient operation of highbrightness (HB) LEDs from voltage sources ranging from 10VDC up to 600VDC.

TJ9910A controls an external MOSFET at fixed switching frequencies up to 120 kHz.

The frequency can be programmed using a single
