- Create a Custom Design Using the LMZ34002 With the WEBENCH® Power Designer
The LMZ34002 SIMPLE SWITCHER® power module is an easy-to-use, negative output voltage power module that combines a 15-W DC-DC converter with a shielded inductor, and passives into a low profile, QFN package. This total power solution allows as few as five external components and eliminates the loop compensation and magnetics part selection process.
The 9×11×2.8 mm QFN package is easy to solder onto a printed circuit board and allows a compact design with fewer components and excellent power dissipation capability. The LMZ34002 offers the flexibility and the feature-set of a discrete design and is ideal for powering a wide range of ICs and analog circuits requiring a negative output voltage. Advanced packaging technology affords a robust and reliable power solution compatible with standard QFN mounting and testing techniques.
