OB3379YCPA-D
Key Features
- 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.
- LED open loop protection OB3379X offers comprehensive protection features to protect the system in various fault to conditions such as Diode & Inductor short protection, CS open protection, LED+/LED- short l protection, LED open loop protection, Over tia temperature protection (OTP). The cycle-by-cycle current limit function limits the maximum current n flowing through the external MOSFET. fide OB3379X is offered in SOP8 package.
- Cycle-by-cycle current limiting
- Built-in leading edge blanking (LEB)
- VIN under voltage lockout with hysteresis
