Working Principles

The STLDC08PUR is a DC-DC buck converter that operates on the principle of pulse width modulation (PWM). It converts a higher input voltage to a lower output voltage by rapidly switching the input voltage on and off. This switching action is controlled by an internal oscillator, which adjusts the duty cycle of the switch to regulate the output voltage. The converter uses inductors and capacitors to store and transfer energy efficiently.
