Working Principles

The MAX5035DASA-T is a step-down DC-DC converter that converts a higher input voltage to a lower output voltage. It utilizes a high-frequency switching technique to efficiently regulate the voltage. The input voltage is connected to the VCC pin, and the desired output voltage is set using the feedback (FB) pin. The enable (EN) pin controls the converter's operation.

When enabled, the MAX5035DASA-T regulates the output voltage by adjusting the duty cycle of the internal switch (SW). It employs a control loop that continuously monitors the output voltage and adjusts the switch accordingly to maintain the desired voltage level. The soft-start/ tracking (SS/TRK) pin allows for gradual startup and synchronization with other power supplies.
