The OB3362F is a highly integrated and high performance LED driver that optimized for LCD
backlight application. It integrates a boost driver and 4 channels of current balancer that optimized
to drives multi LED arrays, and thus provides a high performance LED backlight solution with minimized BOM count.

The OB3362F contains a PWM boost driver which uses current mode control and fixed frequency
operation. The operation frequency can be programmed by setting external resistor value at RI pin.




1. 10V gate drive, better MOS compatibility
