Working Principles

The MAX15025HATB+T is a step-down converter that efficiently converts a higher input voltage to a lower output voltage. It utilizes an integrated power MOSFET and internal compensation to regulate the output voltage with excellent line and load regulation. The device operates at a high switching frequency of 500kHz, enabling compact external components.

When enabled, the input voltage is stepped down by the internal power MOSFET and delivered to the output pin. The feedback pin monitors the output voltage and adjusts the duty cycle of the power MOSFET to maintain a stable output voltage. The soft-start feature ensures a controlled startup, while the power good pin provides an indication of the output voltage status.
