Texas Instruments DC/DC Synchronous Buck Controller 6V to 42V 12A

Texas Instruments DC/DC Synchronous Buck Controller delivers up to 12A of output current in typical applications, operating from a wide 6V to 42V input voltage range.

Overview

This synchronous step-down controller from Texas Instruments is designed for power supply designs that require robust performance. It supports an adjustable output voltage down to 0.6V, making it suitable for a broad range of designs.

The controller uses a constant on-time (COT) control architecture with a proprietary emulated ripple mode. This enables stable operation with low ESR output capacitors, which reduces the overall solution size and output voltage ripple while providing an ultra-fast transient response. Thanks to its COT regulation, no loop compensation is required, which significantly reduces external component count and simplifies the design process.
