XZ3001
Fully integrated 3A power module with built-in inductor and compensation for simplified power supply design
Product Overview
Description
The XZ3001 is a fully integrated power module that includes the DC-DC converter, optimized inductor, and compensation components in a single package. This eliminates the need for external inductor selection and complex compensation design.
The module delivers up to 3A output current from a 2.5V to 5.5V input. It features high efficiency up to 94% and requires only input and output capacitors for a complete power solution.
Available in a compact 4mm x 4mm QFN package, the XZ3001 significantly reduces design time and ensures optimal performance. It is ideal for applications where time-to-market is critical or power supply design expertise is limited.

FAE Expert Insights
"The XZ3001 power module is a game-changer for teams without dedicated power supply engineers. The integrated inductor and compensation eliminate the most challenging aspects of DC-DC design. I've recommended this to several customers who needed to get to market quickly, and the results have been excellent. The efficiency is nearly as good as discrete designs, and the thermal performance is surprisingly good thanks to the optimized internal layout. One thing to note: the package is taller than discrete solutions due to the integrated inductor, so verify height constraints in your mechanical design. For rapid prototyping or designs where you want guaranteed performance without extensive validation, this module is an excellent choice."

Frequently Asked Questions
What are the advantages of using a power module?
Power modules offer several advantages: 1) Simplified design - no inductor selection or compensation calculation needed, 2) Faster time-to-market - guaranteed performance without extensive validation, 3) Smaller solution size - optimized integration saves board area, 4) Better reliability - factory-tested and optimized design. The trade-off is slightly higher cost compared to discrete solutions.
Use power modules for fastest time-to-market and simplified design; use discrete solutions for cost optimization.
What external components are needed with XZ3001?
XZ3001 requires only input and output capacitors for a complete power solution. The inductor and compensation network are integrated inside the module. Typically, a 22μF input capacitor and 22μF output capacitor are sufficient. This significantly reduces BOM complexity compared to discrete designs.
Only 2 capacitors needed; use ceramic capacitors with X5R or X7R dielectric for best performance.
How does the efficiency compare to discrete solutions?
XZ3001 achieves up to 94% efficiency, which is comparable to well-designed discrete solutions. The integrated inductor is optimized for the converter, ensuring good efficiency. While discrete designs can potentially achieve slightly higher peak efficiency with careful optimization, the module provides guaranteed good efficiency without design effort.
Module efficiency is comparable to discrete; choose module for guaranteed performance without design effort.
What is the height of XZ3001 package?
XZ3001 is available in a 4mm x 4mm QFN package with a height of 2.5mm. The height is greater than discrete solutions due to the integrated inductor. Verify this meets your mechanical constraints before selecting the module.
Verify 2.5mm height meets your mechanical constraints; consider discrete solution if lower height is required.
Can I adjust the output voltage of XZ3001?
Yes, XZ3001 features adjustable output voltage set by external resistor divider. The output can be set from 0.8V to 3.3V. This flexibility allows the same module to be used for various voltage rail requirements in your system.
Use resistor divider to set desired output voltage; calculate values using feedback reference voltage from datasheet.
