NCP6922CDMTTXG

Overview

The NCP6922CDMTTXG is a Mini PMIC from onsemi, integrating dual DC-DC buck converters and two LDO regulators within a compact WQFN-20 package. It features switching frequencies of 3 MHz for the DC-DC sections and operates with an input voltage range of 2.3 V to 5.5 V. The device provides high-efficiency power conversion suitable for space-constrained portable applications.

Feature Summary

• Integrates dual synchronous buck converters and dual low-dropout linear regulators in a single chip.
• Utilizes a 3 MHz switching frequency to minimize external component size.
• Features a compact WQFN-20 footprint designed for dense board layouts.

Applications

• Portable consumer electronics requiring multi-rail power supplies
• Smartphones and mobile communication devices
• Tablets and handheld computing devices

Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited supply. Confirm RoHS compliance and specific ordering suffixes against official manufacturer documentation before finalizing procurement plans.

Selection Notes

Select this part when a combination of switching efficiency and low-noise linear regulation is required in a minimal footprint. Ensure the application input voltage falls within the specified 2.3 V to 5.5 V range and thermal constraints are met for the WQFN-20 package.

Part Context

This component belongs to the NCP6922C series of Mini PMICs from onsemi. These devices are engineered to consolidate multiple power rails into a single solution, reducing bill-of-materials complexity and board area compared to discrete regulator implementations.

Replacement Considerations

Check for direct pin-to-pin replacements within the NCP6922 family, such as NCP6922CBMTTXG, ensuring output configurations match requirements. Verify functional equivalence through updated datasheets before substitution.
