GENERAL DESCRIPTION  
The ADP2360 is a high efficiency, high input voltage, discontinu-  
ous 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 mA 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 to optimize the efficiency for the application operat-  
ing conditions and minimize the compatible inductor size.  
The ADP2360 further offers a power-good (PG) pin to indicate  
when the output voltage is good. Other key features include 100%  
duty cycle operation, precision enable control, external soft start  
control, UVLO, and TSD protection.  
The ADP2360 requires no external compensation and the solution  
for the fixed output voltage options requires a minimum of three  
external components. The ADP2360 is available in a 3 mm × 3 mm,  
8-lead LFCSP package with an operating junction temperature  
range from −40°C to +125°C.  
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
