Working Principle

The MAX8878EUK50+T is designed to convert a higher voltage DC voltage to a lower one by switching the higher voltage off for part of the cycle and then on for part of the cycle. During the off cycle, the high voltage is switched off, and part of the input current is diverted to the load. During the on cycle, the high voltage is switched on and the rest of the input current is supplied to the load. This process results in a low output voltage that is capable of supplying high current.

The MAX8878EUK50+T is designed for high input voltage and wide input voltage range applications. It also provides an adjustable output current limit and an adjustable output voltage with minimum ripple. Its PWM technology supports low switching noise, high conversion efficiency, and fast transient response. Additionally, it offers reverse current protection and an integrated driver circuit that reduces heatsinks and other components and offers space savings.
