The NCP1650DR2G is an integrated circuit (IC) component that is widely used in power management applications. It is a pulse width modulation (PWM) controller designed specifically for offline flyback converters. The device operates at a fixed frequency which is internally set to 67kHz.
Key features of the NCP1650DR2G include:
1. Wide Input Voltage Range: The IC can handle a wide input voltage range, from 9V to 36V, which makes it suitable for various power management applications.
2. Active Burst Mode: The NCP1650DR2G features an active burst mode in light load conditions, which helps to improve overall efficiency and reduce power consumption. The active burst mode automatically activates when the load falls below a predetermined threshold.
3. Accurate Constant Voltage (CV) and Constant Current (CC) Regulation: The IC allows accurate regulation of output voltage and current, making it well-suited for applications that require precise control.
4. Overvoltage Protection (OVP): The NCP1650DR2G includes an OVP feature, which ensures that the output voltage does not exceed a certain threshold. This offers protection to both the IC itself and the external circuitry.
5. Frequency Jittering: The device employs frequency jittering technique to reduce electromagnetic interference (EMI) emissions. This helps the end-product to meet regulatory standards regarding electromagnetic compatibility
