Working Principles

The MAX662ACSA+T is a step-up voltage converter that converts a low input voltage to a higher output voltage. It utilizes a switching regulator topology to achieve high efficiency conversion. The input voltage is applied to the VIN pin, and the output voltage is obtained from the VOUT pin. The switching node (SW) controls the flow of current through an inductor, which stores energy during the on-time and releases it during the off-time. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the switching transistor to maintain a stable output. The enable pin (EN) allows for device control, enabling or disabling the converter as needed.
