OB3379YCPA-D
DESCRIPTION
FEATURES
The OB3379X is a high efficiency LED driver designed for white LEDS lighting and backlight. OB3379X is built-in a quasi-resonant control method buck DC/DC converter. 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 bination dimming
- Zero voltage signal detected to improve efficiency and EMI performance
- LED+/LED- short circuit protection and the duty cycle at HPWM pin.
- LED open loop protection
OB3379X offers prehensive protection features to protect the system in various fault to conditions such as Diode & Inductor short protection, CS open protection, LED+/LED-...
