MCZ33998EG

Overview

The MCZ33998EG is a power management integrated circuit from NXP Semiconductors, housed in a 24-SOIC package. It integrates one charge pump and two linear regulators (LDOs) to provide three output channels. The device operates with a switching frequency of 750kHz. It supports an operating temperature range from -40°C to 125°C and utilizes surface mount mounting technology.

Feature Summary

• Integrates mixed-mode power regulation combining a single charge pump stage with two low-dropout linear regulator stages within a single component.
• Provides three distinct regulated output channels suitable for powering multiple subsystems requiring different voltage levels or noise profiles.
• Designed for automotive-grade reliability with extended industrial temperature operation capabilities.

Applications

• Automotive infotainment systems requiring clean power for sensitive analog circuits
• Vehicle body control modules needing combined switched and linear regulation
• Industrial control units requiring robust power management in harsh environments

Procurement Notes

Verify the exact suffix and revision level against official NXP documentation before procurement, as obsolete status may affect availability. Confirm that the 24-SOIC footprint matches your PCB design constraints. Ensure the supplier provides traceability documents for automotive-grade components. Check for any specific handling requirements due to the mixed-signal nature of the device.

Selection Notes

Select this component when a compact solution is needed to combine charge pump and LDO functionalities. It is appropriate for designs requiring three outputs with varying ripple and noise specifications. Consider the 750kHz switching frequency for EMI compatibility. Evaluate thermal performance within the 24-SOIC package for your specific load conditions.

Part Context

This part belongs to NXP's PMIC portfolio, specifically designed for applications requiring mixed regulation topologies. It serves as a consolidated power solution, reducing board space compared to discrete implementations. The integration of charge pump and linear regulators allows for efficient voltage translation and noise-sensitive supply generation.

Replacement Considerations

Check NXP's official obsolescence notices for recommended alternatives. Verify pin-to-pin compatibility if substituting with other triple-output PMICs. Ensure replacement parts support the same 24-SOIC package and temperature range. Consult distributor databases for current stock status of potential substitutes.
