Working Principles

KA5L0365RN is a power switching regulator that utilizes pulse width modulation (PWM) technique to regulate the output voltage. It integrates a power MOSFET and a PWM controller on a single chip. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the PWM signal to maintain a stable output. The switching transistor (Drain) controls the flow of current from the input to the output based on the PWM signal.
