BL0200C
Overview
BL0200 series are 2ch output LED driver IC for LED backlight, and it can do dimming to 0.02 % by external PWM signal. This IC realizes a high efficiency by the boost convertor control that absorbs variability on VF.
- Current-Mode type PWM Control
- PWM frequency is 100 kHz o r 200 kHz
- Maximum On Duty is 90 % LED current control
- Individual PWM Dimming Control
- Analog Dimming
- High contrast ratio is 1 / 5000
- Accuracy of Reg output voltage is ± 1.5 % or ± 2 % Protection functions
- Enable Function of IC (BL0202B, BL0202C)
- Error Signal Output (BL0200C)
- Overcurrent Protection for Boost Circuit (OCP) Pulse-by-pulse
