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

output voltage models.

The ADP2360 uses a single-pulse PFM architecture with an

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.
