4 Control – Mode Architecture

This section provides insight into the different control mode architectures and how to select the right one.

Choosing the Right Variable-Frequency Buck-Regulator Control Strategy:SLUP319

This paper shifts focus to variable frequency control with a discussion of constant on-time control and its enhancements, along with various versions of the D-CAP architecture. The highlights and challenges for each technique are discussed.

Choosing the Right Fixed-Frequency Buck-Regulator Control Strategy:SLUP317

In this paper, the operation and basic design considerations of a buck converter are reviewed. The topic then examines the trade-offs between two fixed-frequency control strategies and some enhancements to extend their capabilities. Basic voltage mode control is adapted with input voltage feed-forward and current mode control is enhanced with emulated current mode control. The highlights and challenges for each technique are discussed and select design examples are presented.

Internally Compensated Advanced Current Mode (ACM) Overview:SLYY118

New low-noise DC/DC control mode benefits enterprise rack server and hardware accelerator applications that need fast transient response as well as active antenna systems (AAS) requiring fixed-frequency modulation and synchronization.

High-efficiency, Low-ripple DCS-Control™ Offers Seamless PWM/power-save Transitions:SLYT531

This article discusses how the DCS-Control™ topology works, demonstrating its low output-voltage ripple in power-save mode, its superb transient response, and its seamless mode transitions.

Understanding Frequency Variation in the DCS-Control™ Topology:SLYT646

This document explains the principles behind the DCS-control™ topology switching frequency variation. It shows that while the switching frequency does vary, this variation is understood, controlled, and usually sufficient for automotive and other frequency-sensitive applications.

Control-Mode Quick Reference Guide:SLYT710

TI is active in the development of leading-edge control circuits to help engineers address specific design challenges. Since no control mode is optimal for every application, various control modes for non-isolated step-down controllers and converters are referenced with their advantages and how to learn more about each mode. The TI portfolio contains 12 types of control architectures for non-isolated TPS- and LM-series switching DC/DC converters and controllers.
