Part number : OB3362RP
Functions : 4 Channels High Performance LED Driver
Manufacturer : On-Bright Electronics
OB3362FRP is Marking OB3362RP.
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
The OB3362F integrates 4 channels current balancer with up to 200mA current capability per channel and it can achieve 3% matching accuracy among LED strings. The minimum voltage of current source is regulated to as lower as 350mV, which benefits the efficiency and improves the IC thermal performance.
The OB3362F supports external PWM dimming and internal burst dimming mode which allow flexible control of the backlight luminance. The LED current is directly modulated by external PWM duty cycle when PWM dimming mode is selected. The LED current can be adjusted by an external DC voltage when internal burst dimming mode is selected.
