TPS564201DDCR

TPS564201DDCR is the tape-and-reel SOT-23-THIN (DDC) ordering code for the Texas Instruments TPS564201 synchronous step-down converter, listed by TI as Active / Production in the current package option addendum. It accepts an input from 4.5 V to 17 V, sets its output between 0.76 V and 7 V, delivers 4 A, switches at 500 kHz to 600 kHz (560 kHz typical), draws 400 µA typical quiescent current and under 5 µA in shutdown, integrates MOSFETs of 50 mΩ (high side) and 22 mΩ (low side), holds feedback accuracy to 1.6 % at 25 °C and starts on a fixed 1.0 ms soft-start. The selection point is 4 A from a six-pin package: point-of-load rails for processors, FPGAs and industrial controllers fit the SOT-23-class footprint instead of a larger power package. Selection advice: this is the 4 A TPS564201, not the 3 A TPS563201 also listed in this catalog - the two share a package style and a near-identical name but differ in current rating, switching frequency and MOSFET resistance, so the full code must be matched character for character. Parameters verified against the TI TPS564201 datasheet SLVSD91 and the current package option addendum.
