Product Description

The LMZ31503RUQT is a SIMPLE SWITCHER® Power Module combines a 3A DC/DC converter with power MOSFETs, a shielded inductor and passives into a low profile. This is an easy-to-use integrated power solution. This total power solution allows as few as 3 external components and eliminates the loop compensation and magnetic design process. It is easy to solder onto a printed circuit board and allows a compact point-of-load design with up to 95% efficiency and excellent power dissipation with thermal impedance of 13°C/W junction to ambient. The device delivers the full 3A rated output current at 85°C ambient temperature without airflow. The LMZ31503 offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering performance DSPs and FPGAs.
Complete integrated power solution allows small footprint, low-profile design
Synchronizes to an external clock
Adjustable slow-start
