3 Introduction

The UCD3138x family of digital power controllers offer superior levels of integration and performance in a single-chip solution. The UCD3138x devices are flexible and are designed for a wide variety of power conversion applications. In addition, multiple peripherals inside the device have been specifically optimized to enhance the performance of AC-DC and DC-DC applications, and to reduce the total component count.

The UCD3138x devices are a fully programmable power controller offering customers complete design control and autonomy. With high levels of configuration, complex firmware is not needed. TI simplifies our customers’ development with integrated and easy-to-use tools. The UCD3138x devices can be programmed using TI’s Code Composer Studio™ (CCS) Integrated Development Environment (IDE) or our powerful Fusion Digital Power Studio Graphical User Interface (GUI) Suite. Thus, customers receive the power and flexibility of digital control without the challenge of complex firmware.

At the core of the UCD3138x devices are the digital control loop peripherals, also known as Digital Power Peripherals (DPPs). These DPPs are high-speed digital control loops independent of the internal microcontroller (MCU). Each DPP consists of an Error Analog-to-Digital Converters (EADC), a PID-based compensator, and DPWM outputs. The UCD3138x devices also have general-purpose ADCs for real-time sensing. Lastly, the UCD3138x devices can communicate to external peripherals via Universal Asynchronous Receiver/Transmitter (UART), Inter-Integrated Circuit (I2C) or Power Management Bus (PMBus). All the processes are managed by the internal 32-bit Arm®7 MCU using programmable flash memory or on-chip RAM/ROM.
