This section discusses how to use the UCD3138x devices in various power converters and how these devices can improve your design.

The UCD3138x devices excel in a wide variety of applications. Five of the main categories are highlighted below:

  • Multiple Series Power Stages
  • Multiple Parallel Power Stages
  • High Performance
  • External Communication
  • High Power Density

The UCD3138x devices achieve high performance and high flexibility with a dedicated hardware-based power stage controller. This is a configurable control loop that is etched into the silicon and is independent from the MCU. Thus, the control loop is easy to configure and is not limited by the MCU bandwidth.
