GENERAL DESCRIPTION:
The MSN12AD60-RUD is a digital synchronous DC/DC
power module. The digital controller, power MOSFETs and
most of support components are integrated in one hybrid
package.
The module allows system telemetry (remote
measurement and reporting) of current, voltage, and
temperature information through its serial interface.
Additionally, to maximize system performance and
reliability, the module provides temperature
correction/compensation of several parameters. The
module is a fully protected DC/DC solution that utilizes
analog and digital functionality to maximize protection of
the system.
The compact size enables utilization of space for highly
density point of load to save the space and area. The
thermal pad can enhance heat transferring capability. It
is suitable for automated assembly by standard surface
mount equipment and is Pb-free and RoHS-compliance.
