Working Principles

AP1512-12K5L-U operates on the principle of pulse width modulation (PWM) to regulate the output voltage. It uses an internal oscillator to generate a high-frequency signal, which is then fed into a power switch. The power switch controls the duty cycle of the signal, thereby regulating the output voltage. Feedback from the output voltage is continuously monitored and compared to a reference voltage, allowing the device to adjust the duty cycle accordingly.
