NCP6922CCMTTXG

Overview

The NCP6922CCMTTXG is a specialized Power Management IC (PMIC) from onsemi, housed in a 20-WQFN (4x4 mm) package. It integrates four output channels: two DC-DC buck converters and two Low Dropout (LDO) regulators. The buck outputs provide up to 800 mA with adjustable voltage ranges of 0.6V to 3.3V, while the LDOs deliver 150 mA at fixed voltages between 1V and 3.3V. Operating from a 2.3V to 5.5V supply, it features a 3MHz switching frequency and an 82µA quiescent current.

Feature Summary

• Integrates dual high-current buck converters and dual low-noise LDOs for comprehensive power management
• Supports wide input voltage range suitable for single-cell lithium battery applications
• Features compact WQFN packaging optimized for space-constrained portable designs

Applications

• Portable electronic devices requiring multi-rail power sequencing
• Smartphones and tablets utilizing single-cell lithium-ion batteries
• Wearable technology with strict size and efficiency constraints

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Request original datasheets and material declarations to confirm RoHS compliance and REACH status. Inspect packages for integrity as availability may be limited to surplus stock. Ensure compatibility with existing design specifications before procurement.

Selection Notes

Select this PMIC when designing systems requiring integrated buck and linear regulation within a minimal footprint. Evaluate thermal performance given the 800mA buck capability in a small package. Confirm that the 3MHz switching frequency aligns with electromagnetic interference requirements. Verify that the available output voltages meet the specific load requirements of the target application circuitry.

Part Context

This component belongs to the NCP6922C series of mini PMICs designed for mobile applications. It consolidates multiple power stages into a single chip to reduce board space. The series is characterized by high integration and low standby current, targeting battery-powered consumer electronics where efficiency and size are critical design parameters.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is discontinued, engineering teams must evaluate alternative PMICs from current portfolios. Cross-reference pinouts, electrical characteristics, and thermal properties carefully during any transition planning.
