The LMZ35003 Power module is an easy-to-use integrated power solution that integrates 2.5a DC/DC converters with shielded inductors and passivity into a low-profile QFN package. This total power solution allows only five external components and eliminates loop compensation and the magnetic part selection process.
Simplified Application
The LMZ35003 offers the flexibility and feature set of a discrete point of load design and is ideal for powering a wide range of ics and systems. Advanced packaging technology provides a powerful and reliable power solution compatible with standard QFN installation and testing techniques.
Functional block diagram
The QFN package size is 9 mm x 11 mm x 2.8 mm, easy to solder onto the printed circuit board and allows for compact point-of-load design with over 90% efficiency and excellent power consumption capability.
