Overview
The ADP2360ACPZ-R7, produced by Analog Devices Inc., is a high-efficiency, high-input-voltage, discontinuous conduction mode (DCM) synchronous step-down dc-to-dc switching regulator. This regulator operates with a wide input voltage range from 4.5 V to 60 V and can source up to 50 mA continuous output current, making it ideal for regulating power from various voltage sources in space-constrained applications. The ADP2360 is available in adjustable output (0.8 V to VIN) or fixed output voltage models (3.3 V and 5.0 V). It is packaged in a 3 mm × 3 mm, 8-lead LFCSP package with an operating junction temperature range from −40°C to +125°C.
