Working Principles

The STM1403ATNQ6F is a step-down (buck) DC-DC converter. It takes an input voltage within the specified range and efficiently converts it to a lower, regulated output voltage. The integrated circuit uses a switching regulator topology to achieve high efficiency. It employs pulse-width modulation (PWM) techniques to control the duty cycle of the internal power switch, regulating the output voltage. The feedback loop continuously monitors the output voltage and adjusts the duty cycle accordingly.
