ADP2360ACPZ-5.0-R7

Conv DC-DC 4.5V to 60V Step Down Single-Out 5V 0.05A 8Pin LFCSP EP T/R

Product Details

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 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 uses a single-pulse PFM architecture with adjustable IPEAK control to minimize the input and output ripple. The adjustable IPEAK current limit allows the ADP2360 to optimize the efficiency for the application operating 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, undervoltage lockout, and thermal shutdown.

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.
