FAE Expert Insights
"The XZ3002 is perfect for applications where space is extremely limited. The 3mm x 3mm package is incredibly small for a complete power solution. I've used this in wearable designs where every square millimeter counts. The fixed voltage options are convenient - no need for external resistors, saving even more space. Efficiency is good at 93%, though slightly lower than the larger XZ3001 due to the smaller inductor. The 2.5MHz switching frequency keeps external components small. One consideration: the smaller package has slightly lower thermal capability, so ensure your maximum load and ambient temperature are within spec. For low-power portable devices, this module is an excellent choice."

Frequently Asked Questions
How small is the XZ3002 power module?
XZ3002 is available in a tiny 3mm x 3mm QFN package. This ultra-compact size includes the DC-DC converter, inductor, and compensation components. The small size makes it ideal for wearable devices, IoT sensors, and other space-constrained applications.
Use XZ3002 for minimum size requirements; verify height constraints as integrated inductor adds thickness.
What is the difference between XZ3001 and XZ3002?
XZ3001 is a 3A power module in a 4mm x 4mm package, while XZ3002 is a 2A module in a 3mm x 3mm package. XZ3001 offers higher current capability and slightly better efficiency, while XZ3002 offers smaller size. Choose based on your current requirements and space constraints.
XZ3001 for higher current (3A) and efficiency; XZ3002 for minimum size (3mm x 3mm) with 2A capability.
Are fixed output voltage versions available?
Yes, XZ3002 is available in fixed output voltage versions (1.0V, 1.2V, 1.8V, 3.3V) that don't require external resistors. This saves additional board space and simplifies BOM. Adjustable versions are also available for flexibility.
Use fixed voltage version for smallest size and simplest design; adjustable version for flexibility.
What is the thermal performance of XZ3002?
XZ3002 has good thermal performance for its size, with thermal resistance of approximately 40°C/W. At 2A output with 5V input and 3.3V output, power dissipation is about 1.7W, resulting in temperature rise of approximately 68°C. Ensure adequate PCB copper area for heat dissipation.
Use adequate PCB copper area for heat dissipation; verify maximum junction temperature is not exceeded at full load.
Can XZ3002 be used in battery-powered applications?
Yes, XZ3002 is well-suited for battery-powered applications. The 2.5V to 5.5V input range covers single Li-ion battery operation. The high efficiency (up to 93%) maximizes battery life. The compact size is ideal for portable devices where space and weight are critical.
XZ3002 is excellent for battery-powered designs; verify efficiency at your operating points for battery life calculations.
