Overview
The PM823UK/A0CZ is a specialized Power Management IC (PMIC) from NXP Semiconductors, designed for professional power management applications. It integrates two synchronous 1.5A step-down buck regulators and a 525 mA Low Dropout (LDO) regulator within a single WLCSP-12 package. The device operates with an input voltage range of 1.6 V to 5.5 V, supporting output voltages adjustable from 600 mV to 3.3 V. It functions reliably across a temperature range of -40°C to +85°C and utilizes surface-mount technology.
Feature Summary
- Integrates dual synchronous 1.5A buck converters and a 525mA LDO in a compact footprint
- Supports wide input voltage range from 1.6V to 5.5V for flexible system design
- Optimized for space-constrained portable and IoT applications
Applications
- IoT devices
- Wi-Fi modules
- Smart home devices
Procurement Notes
Verify component status as the PM823UK/A0CZ is listed as discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market sources if procurement is required. Ensure compatibility with existing designs before sourcing obsolete inventory. Check RoHS compliance details via official documentation prior to integration.
Selection Notes
Select this PMIC for systems requiring multiple regulated rails from a single compact component. The integrated buck regulators provide efficient power conversion for digital loads, while the LDO supports noise-sensitive analog circuits. Consider the WLCSP-12 package constraints during PCB layout. Evaluate thermal performance given the high current capabilities in a small form factor.
Part Context
This component belongs to the PM823 series of power management ICs from NXP Semiconductors. It is categorized under specialized PMICs intended for professional applications. The part represents a solution for consolidating power regulation functions into a minimal board area, suitable for modern electronic devices where space efficiency is critical.
Replacement Considerations
As the PM823UK/A0CZ is discontinued, identify alternative PMICs with similar dual-buck and LDO configurations. Verify pinout compatibility and electrical specifications such as current ratings and input voltage ranges. Consult NXP's official substitution guides or contact sales channels for recommended legacy replacements.
