The TPS562200DDCR is a high-current, synchronous step-down DC-DC converter from Texas Instruments, designed to deliver up to 4A of continuous output current with high efficiency across a wide input voltage range of 4.5V to 38V. Housed in a compact DQFN-20 package, this device supports adjustable output voltages from 0.8V to VIN (regulated), making it ideal for power-hungry applications in industrial, automotive, and server systems. Its integrated high-side and low-side MOSFETs minimize external component count while ensuring robust performance under heavy loads.

Key Features

Operating at a fixed switching frequency of 550 kHz, the TPS562200DDCR achieves efficiencies exceeding 90% under nominal loads, thanks to its advanced current-mode control and low quiescent current (typically 12 µA in shutdown mode). It features programmable soft-start, output voltage tracking, and adjustable slope compensation for stable operation in high-duty-cycle conditions. The device includes comprehensive protection features such as overcurrent protection (OCP), overtemperature shutdown (OTS), and under-voltage lockout (UVLO). Its wide input voltage tolerance accommodates unregulated power sources or noisy industrial environments.

Applications

Primarily used in industrial automation, server power rails, and automotive infotainment systems, the TPS562200DDCR efficiently powers FPGAs, GPUs, and other high-current digital loads. Its capability to handle input voltages up to 38V makes it suitable for automotive 12V/24V systems and industrial 24V rails. It is also employed in telecom infrastructure, LED lighting drivers, and battery-operated equipment requiring stable, high-current outputs. Its compact size and high power density enable integration into space-constrained designs without compromising thermal performance.

Summary

The TPS562200DDCR excels in high-current, wide-input-voltage applications with its combination of high efficiency, robust protection, and compact form factor. Its integrated MOSFETs and advanced control features simplify design complexity while ensuring reliable operation in harsh environments. This converter is a key choice for engineers needing a versatile, high-performance solution to power dense, power-hungry systems across industrial, automotive, and data center markets.
