Overview
The PM823HN/A0CHP is a specialized Power Management IC (PMIC) from NXP Semiconductors, designed for professional power management applications. It integrates dual synchronous 1.5A step-down buck regulators and a 525 mA Low Dropout (LDO) regulator within a single compact 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 an industrial temperature range of -40°C to +85°C, making it suitable for space-constrained IoT devices, Wi-Fi modules, and smart home systems.
Feature Summary
- Integrates two high-current synchronous buck converters and one LDO in a single chip
- Optimized for compact form factors using WLCSP packaging
- Supports wide input voltage ranges for flexible system design
Applications
- IoT devices
- Wi-Fi modules
- Smart home devices
Procurement Notes
Verify the specific suffix HN/A0CHP against official NXP documentation to confirm exact electrical tolerances and package variants. Confirm current availability status as distribution channels may list this part as discontinued or obsolete. Ensure compliance with RoHS directives and check for any specific handling requirements associated with the WLCSP format during assembly.
Selection Notes
Select this component when board space is limited and multiple regulated rails are required from a single source. It is appropriate for designs needing 1.5A continuous current from buck outputs and moderate current from the LDO. Consider thermal dissipation capabilities within the small footprint and ensure the input supply voltage remains within the specified 1.6 V to 5.5 V window for stable operation.
Part Context
This part belongs to the PM823 series of PMICs from NXP Semiconductors. The series is engineered for portable and embedded electronics requiring efficient power conversion in minimal areas. The HN/A0CHP designation indicates a specific configuration within this family, tailored for professional power management tasks in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers for PM823HN/A0CHP are not available in the provided reference data. Consult NXP sales channels for direct cross-references or updated product line replacements.
