The ADP2360ACPZ-R7 is a high efficiency, high input voltage, discontinuous conduction mode (DCM) synchronous, step-down, dc-to-dc switching regulator. The ADP2360ACPZ-R7 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 ADP2360ACPZ-R7 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 ADP2360ACPZ-R7 uses a single-pulse PFM architecture with adjustable IPEAK control to minimize the input and output ripple. The adjustable IPEAK current limit allows the ADP2360ACPZ-R7 tooptimize the efficiency for the application operating conditions and minimize the compatible inductor size.
The ADP2360ACPZ-R7 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 ADP2360ACPZ-R7 requires no external compensation and the solution for the fixed output voltage options requires a minimum of three external components. The ADP2360ACPZ-R7 is available in a 3 mm × 3 mm, 8-lead LFCSP package with an operatingjunction temperature range from −40°C to +125°C.
