Dual Channel High Efficiency and High Accuracy Average

Current Control LED Backlight Buck Controller

General Description

Features

^zFast Average Current Control T²C (T1/T2 Average

The RT6010 is a dual channel high accuracy average current

control LEDbacklight buck controller for 2 LEDstrings w/

o LED binning. Dual MOSFET drivers are specifically

designed to drive two power N-MOSFETs in an

asynchronous buck converter topology. The controller

provides variable LED current control by adjusting the CS

resistor value for digital and linear dimming. The controller

operates with T1/T2Average Current Control (T²C) topology

to provide high accuracy 3%. The controller also provides

high efficiency (higher than 95%) under proper setting

without LED binning. The controller provides V_INfrom 8V

to 450V. It is preferred to operate the controller under a

current ripple of < 30% average current and about 85%

duty to optimize the performance.

^zProvide High Efficiency > 95% and High Accuracy

3% Channel to Channel Variation

^zProvide LED w/o Binning

^zProgrammable PWM Constant Off Time

^zSupport both PWM and Analog Dimming

^zPWM Dimming Duty Down to 1%

^zOVP for Bar Short with V_IN

z UVP for Bar Open/Short to GND with

programmable Fault Delay

z Support SPD (Smart Phase Shift Dimming) for

Multiple Channel Dimming Solution

z V_INPOR Detection with EN Pin to Prevent

Malfunction

The RT6010 can be easily connected in series by master/

slave synchronization for multiple channel, even for more

than 6-CH. The controller provides SPD(Smart Phase Shift

Dimming) that is easily implemented to synchronize master

and slave ICs. The controller provides both analog and

PWM dimming.

z SOP-16 Package

z RoHS Compliant and Halogen Free

Applications

The RT6010 automatically detects LED bar open, LED

bar short to V_IN, and LED bar short to GND to prevent

VOUT from over/under voltage damages. The controller

also outputs fault signal with programmable delay to

previous power stage, such asACDC controller.
