Working Principles

The MAX5035DUSA+ operates as a synchronous buck regulator, converting the input voltage to a lower regulated output voltage. It utilizes pulse-width modulation (PWM) techniques to control the switching of the internal power MOSFETs. The feedback pin (FB) is used to regulate the output voltage by comparing it with an internal reference voltage. The soft-start/ tracking pin (SS/TR) controls the startup behavior, gradually ramping up the output voltage to prevent excessive inrush current.
