open-in-new Find other Buck modules (integrated inductor)


The LMZ36002 power module is an easy-to-use integrated power supply that combines a 2-A DC/DC converter with a shielded inductor and passives into a low profile, QFN package. This total power solution allows as few as three external components while maintaining an ability to adjust key parameters to meet specific design requirements.

The QFN package is easy to solder to a printed circuit board, allows reflow profiles up to 245°C, and has excellent power dissipation capability. The LMZ36002 offers flexibilty with many features and is ideal for powering a wide range of devices and systems.
