Working Principles

The NCP1014ST65T3G is a switching regulator controller that operates in pulse frequency modulation (PFM) mode. It regulates the output voltage by adjusting the duty cycle of the switching transistor. The feedback pin (FB) compares the output voltage with a reference voltage, and the compensation pin (COMP) ensures stability by controlling the loop response. The current sense input (CS) monitors the output current for overcurrent protection. The soft-start and shutdown control pin (SS/TR) provides smooth startup and shutdown operations. The internal high-voltage startup bias supply (HV) enables reliable startup even at low input voltages.
