TPS563201DDCR

TPS563201DDCR is the tape-and-reel SOT-23-THIN 6 (DDC) ordering code for the Texas Instruments TPS563201 synchronous step-down converter, listed by TI as Active. It accepts a 4.5 V to 17 V input, regulates against a 749 mV to 787 mV feedback reference (768 mV typical), switches at 580 kHz typical, limits switch current between 3.3 A and 5.1 A (4.2 A typical), and draws 380 µA typical and 520 µA maximum non-switching input current. The 201 code is the Eco-mode variant of the family, trading a fixed-frequency sibling option for light-load efficiency. The selection point is a wide-input buck in a six-pin thin package: 12 V industrial and consumer rails step down to core and I/O voltages with a small inductor, and Eco-mode operation keeps standby drain low in equipment that idles most of the day. Selection advice: match the 201 suffix to the intended light-load behaviour - the family also offers a forced-continuous-conduction variant under a different suffix, and the two are not behaviourally identical at light loads even though the footprint matches. Parameters verified against the TI TPS563201 datasheet SLVSD90 Rev. B (ordering appendix and electrical characteristics).
