GENERAL DESCRIPTION
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 atRI pin.
