Working Principles
The MAX662AESA+T is a step-up voltage converter that converts a low input voltage to a higher output voltage. It utilizes an internal oscillator and a power switch to regulate the output voltage. The feedback pin (FB) is used to set the desired output voltage, which is then compared with an internal reference voltage. The converter adjusts the duty cycle of the internal switch to maintain a stable output voltage.
