Texas Instruments LMZ34202 SIMPLE SWITCHER® Power Module
Texas Instruments LMZ34202 SIMPLE SWITCHER® Power Module is an easy-to-use integrated power supply. This device combines a 2A 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 260°C, and has excellent power dissipation capability. The Texas Instruments LMZ34202 offers flexibility with many features and is ideal for powering a wide range of devices and systems.
