Working Principles
The MAX5035AUSA+T is a step-down DC-DC converter that efficiently converts a higher input voltage to a lower output voltage. It utilizes a pulse-width modulation (PWM) control scheme to regulate the output voltage. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal switch to maintain the desired voltage level.
When enabled, the converter starts operating by controlling the switch (LX) to deliver energy from the input to the output through an inductor. The soft-start/ tracking pin (SS/TR) allows for controlled startup behavior, preventing excessive inrush current. The power good pin (PG) provides an indication when the output voltage is within the desired range.
