NCP6922CBMTTXG

Overview

The NCP6922CBMTTXG is a specialized Power Management IC (PMIC) from onsemi, housed in a 20-WQFN (4x4 mm) package. It integrates four output channels: two synchronous buck converters and two low-dropout (LDO) regulators. The DC-DC sections operate at a switching frequency of 3 MHz and deliver up to 800 mA each, with adjustable output voltages ranging from 0.6 V to 3.3 V. The LDO outputs provide 150 mA each, supporting fixed voltages between 1 V and 3.3 V. The device functions within an input supply range of 2.3 V to 5.5 V and features a quiescent current of 82 µA.

Feature Summary

• Integrates dual high-current synchronous buck converters and dual precision LDOs in a single compact package
• Utilizes a 3 MHz switching frequency to minimize external passive component size
• Supports flexible voltage configurations with adjustable DC-DC outputs and selectable LDO options
• Designed for ultra-low power consumption with minimal quiescent current draw

Applications

• Portable consumer electronics requiring multi-rail power distribution
• Mobile communication devices needing efficient battery-powered management
• Embedded systems utilizing mixed-signal power architectures
• IoT modules requiring compact form factor power solutions

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix matches the required pinout and thermal characteristics. Check for recent Product Change Notifications (PCN) regarding manufacturing site changes. Ensure compliance with RoHS and REACH regulations as specified in the official datasheet. Validate that the 20-WQFN footprint aligns with your PCB design guidelines.

Selection Notes

Select this PMIC when space constraints require integrating multiple regulator types into one component. It is suitable for designs needing both high-efficiency switching regulation for main rails and low-noise linear regulation for sensitive analog circuits. Consider the 3 MHz frequency if minimizing inductor size is critical. Verify that the total output current requirements fit within the 800 mA buck and 150 mA LDO limits per channel.

Part Context

This component belongs to the NCP6922C series of mini PMICs designed for portable applications. It consolidates power management functions typically spread across multiple discrete components. The series is engineered to reduce board area and simplify BOM complexity. It serves as a central power hub for systems requiring stable, efficient voltage conversion from a single input source.

Replacement Considerations

Check for direct cross-references within the NCP6922 family. Verify pin-to-pin compatibility before substitution. Review updated datasheets for any functional revisions in newer lot codes. Ensure thermal performance remains adequate under load conditions.
