Working Principles

The MAX1976AEZT180+T is a step-down DC-DC converter that utilizes pulse-width modulation (PWM) to regulate the output voltage. It operates by switching the input voltage on and off at a high frequency, which is then filtered and regulated to provide a stable 1.8V output voltage. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the switching signal to maintain the desired voltage level.
