Working Principles

The NCP1076STAT3G is a switching regulator controller that operates in both constant voltage (CV) and constant current (CC) modes. It uses a pulse width modulation (PWM) control scheme to regulate the output voltage. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the PWM signal to maintain a stable output. The compensation pin (COMP) allows for stability control by adjusting the loop response.

The device incorporates overvoltage protection (OVP) and overcurrent protection (OCP) mechanisms to safeguard the system from potential faults. In case of an overvoltage or overcurrent condition, the NCP1076STAT3G shuts down the power supply to prevent damage.

Detailed Application Field Plans

The NCP1076STAT3G is commonly used in various applications, including:

  1. Power adapters
  2. Battery chargers
  3. LED lighting systems
