Working Principles

The MAX253CSA+T is a DC-DC converter controller that utilizes a pulse-width modulation (PWM) technique to regulate the output voltage. It operates by continuously adjusting the duty cycle of the internal power switch to maintain the desired output voltage level. The feedback loop compares the actual output voltage with the reference voltage and adjusts the duty cycle accordingly. This control mechanism ensures stable and accurate voltage regulation.
