GENERAL DESCRIPTION The ADP2360 is a high efficiency, high input voltage, discontinuous conduction mode (DCM) synchronous, step-down, dc-to-dc switching regulator. The ADP2360 operates with a wide input voltage supply range from 4.5 V to 60 V and can source up to 50 m A continuous output current, making it ideal for regulating power from a variety of voltage sources in space-constrained applications. The ADP2360 is available with an adjustable output (0.8 V to VIN) or in 3.3 V and 5.0 V factory-programmable fixed output voltage models. The ADP2360 uses a single-pulse PFM architecture with an adjustable peak current level (IPEAK) control to minimize the input and output ripple. The adjustable IPEAK current limit allows Rev.
