ADD5211 Description
The ADD5211 is a 4 channel, white LED driver for backlight applications based on high efficiency, current mode, step-up converter technology. The boost controller drives an external MOSFET switch for step-up regulation from an input voltage of 4.5 V to 40 V and a pin adjustable operating frequency between 200 kHz and 1.2 MHz. An adjustable UVLO function is implemented to reduce input current during power-off.
