TPS54260QDGQRQ1 – TEXAS INSTRUMENTS

The TPS54260QDGQRQ1 is a 4A synchronous step-down converter from Texas Instruments, housed in a compact 4mm x 4mm QFN (quad flat no-lead) package. Specifically designed for high-efficiency point-of-load (POL) applications, it operates from a 4.5V to 18V input voltage range, delivering a precisely regulated output voltage adjustable from 0.8V to 5.5V. Its internal 2.2MHz switching frequency minimizes external component size, contributing to a highly compact solution._x000D_

Key features include integrated high-side and low-side MOSFETs, enabling high efficiency exceeding 95% at typical operating points, and a programmable soft-start function to reduce inrush current. The device incorporates cycle-by-cycle current limiting and over-temperature protection, ensuring robust operation even under stressful conditions. Its small form factor and high efficiency make it ideal for space-constrained applications in portable devices, industrial controls, and high-density computing systems requiring multiple regulated voltage rails. The TPS54260QDGQRQ1’s precise output voltage regulation and low output voltage ripple are particularly advantageous in sensitive analog circuits. Its ease of use, stemming from minimal external components, reduces design complexity and accelerates time-to-market.
