AP1551 - Brand New Amphenol DC Switching Regulators
-
Description
The AP1551 is a monolithic IC designed for dual channel step-down DC/DC converters. It has the ability to drive a 2A load on each channel without requiring additional transistor components. The AP1551 reduces the number of external components, making it easy to save board space. It features an external shutdown function that can be controlled by logic level, allowing it to enter standby mode. The internal compensation provides good line and load regulation for feedback control without needing external design.
