TPS563231DRLR Synchronous Step-Down Regulator
The TPS563231DRLR from Texas Instruments is a high-efficiency, synchronous step-down DC-DC converter designed to deliver up to 3 A of continuous output current from input voltages ranging from 4.5 V to 17 V. It integrates both high-side and low-side MOSFETs, significantly reducing component count and improving overall system efficiency.
Based on D-CAP3™ control mode, the TPS563231 provides fast transient response, excellent load regulation, and simple compensation-free design, making it ideal for compact and cost-sensitive power solutions. The converter operates at a fixed 600 kHz switching frequency, optimizing size and efficiency when paired with small inductors and ceramic capacitors.
To ensure reliable operation, the device includes comprehensive protection features such as overcurrent protection (OCP), overvoltage protection (OVP), thermal shutdown (TSD), and undervoltage lockout (UVLO). A power-good (PG) signal output is also provided for system monitoring and sequencing control.
With its ultra-compact 6-pin SOT-563 (DRL) package, the TPS563231 enables space-constrained designs, delivering high power density without compromising performance. It is particularly suited for digital televisions, set-top boxes, networking devices, surveillance systems, and other embedded power applications.
