TPS61023DRLR

TPS61023DRLR is the 4,000-piece large tape-and-reel order code for the TI TPS61023, a synchronous boost converter in a 6-pin SOT-563 package (DRL, 1.2 x 1.6 mm) rated -40 to +125 C and listed active in the datasheet package option addendum (SLVSF14 Rev. B). The input operating range is 0.5 V to 5.5 V with an adjustable 2.2 V to 5.5 V output, and the integrated switches are 47 mOhm low-side and 68 mOhm high-side at a 5.0 V output; the efficiency anchor is 94 percent at 3.6 V in, 5 V out and 1.5 A load. Selection advice: two numbers are routinely misread on this part - the 3.7 A figure is the typical valley switch current limit (2.7 A minimum), not an output current rating, and maximum continuous output current must be computed from duty cycle and inductor ripple; and the input needs 1.8 V to start, operating down to 0.5 V only after start-up with the output above 2.2 V, so a cold battery below the start-up threshold will not start the converter. The 250-piece small-reel code is TPS61023DRLT.
