LMZ34002RKGR

The LMZ34002 SIMPLE SWITCHER power module is an easy-to-use negative output voltage power module that integrates a 15W DC/DC converter with a shielded inductor and passive components in a small-outline QFN package. This complete power solution requires only five external components and eliminates the loop compensation and magnetic component selection processes. The 9×11×2.8mm QFN package can be easily soldered to the printed circuit board and enables a compact design with fewer components and excellent power dissipation capabilities. The LMZ34002 offers the flexibility and feature set of a discrete design and is well-suited for powering a variety of ICs and analog circuits requiring negative output voltages. Advanced packaging technology provides a robust and reliable power solution compatible with standard QFN mounting and testing techniques.
