ADP1823ACPZ-R7

Overview

The ADP1823ACPZ-R7 is a dual, interleaved, synchronous step-down DC-to-DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5 V to 20 V and supports adjustable output voltages from 600 mV to 17 V. The device delivers up to 20 A of output current with switching frequencies selectable at 300 kHz or 600 kHz. Packaged in a 32-lead LFCSP_VQ (LFCSP-32) for surface mount installation, it functions across a temperature range of -40°C to +85°C.

Feature Summary

Dual-channel interleaved architecture for high-current applications
Synchronous rectification for enhanced efficiency
Adjustable switching frequency selection

Applications

Industrial power systems
Computing infrastructure
Automatic External Defibrillator (AED) solutions

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific package marking and datasheet revision matches the delivered unit. Ensure storage conditions comply with moisture sensitivity levels to prevent damage prior to soldering. Cross-reference the ordering suffix with official documentation to confirm pinout and electrical specifications.

Selection Notes

Select this controller for designs requiring high output currents up to 20 A with dual-phase capability. It is suitable for applications needing flexible input voltages between 4.5 V and 20 V. Consider the thermal performance of the LFCSP-32 package relative to the expected load. Evaluate the need for external components such as inductors and capacitors based on the chosen switching frequency.

Part Context

This component belongs to the ADP1823 series of power management integrated circuits. It is designed as a high-performance switching controller rather than a complete regulator, requiring external MOSFETs. The part is categorized under DC-DC Switching Controllers within the broader PMIC family offered by Analog Devices.
