FEATURES
DESCRIPTION
•
Complete Integrated Power Solution Allows
Small Footprint, Low-Profile Design
The LMZ35003 SIMPLE SWITCHER® power module
is an easy-to-use integrated power solution that
combines a 2.5-A 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.
