Working Principles

The MAX1697TEUT+T is a step-up DC-DC converter that efficiently boosts low input voltages to higher output voltages. It utilizes a switching regulator topology to achieve high efficiency and low power dissipation. The converter operates by rapidly switching an inductor on and off, storing energy during the on-time and releasing it to the output during the off-time.

The input voltage is regulated and converted to a higher output voltage through a feedback mechanism. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the switching regulator to maintain a stable output voltage.
