The UCD3138128A is a functional variant of the UCD3138 Digital Power Controller that includes significant

improvements over the UCD3138. For a description of the complete changes made in the UCD3138128A, refer

to UCD3138128A Migration Guide. The major improvements are:

•

The General Purpose ADC has been improved for better accuracy and performance at extreme cold

temperatures (–40°C).

•

The UART peripheral has been modified to include a hardware based auto-baud rate adjustment feature.

•

A new Synchronous Rectifier Dead Time Optimization hardware peripheral has been added. Benefits include:

–

Improved efficiency

–

Reduced synchronous rectifier voltage stresses

–

Shorter development cycle

•

A Duty Cycle Read Function has been added to improve use in peak current mode.
