On-Bright OB3379YCPA-D
The OB3379X is a high efficiency LED driver designed for white LEDS lighting and backlight. The controller implements a peak current mode control scheme Low system cost and high efficiency Quasi-Resonant buck topology operation Programmable CC regulation 1%-100% Analog and PWM to analog and an internal transconductance amplifier to accurately control the output current over a wide input and load conditions. The transconductance amplifier reference is set by internal reference voltage which determined by the input of ADIM pin combination dimming Zero voltage signal detected to improve efficiency and EMI performance LED+/LED- short circuit protection and the duty cycle at HPWM pin.
