LMR16006XDDCR

LMR16006XDDCR is the tape-and-reel SOT-23-THIN 6 (DDC) ordering code for the Texas Instruments LMR16006 step-down converter, listed by TI as Active. The X in the ordering name is the fixed 0.7 MHz frequency variant - the Y variant of the same family runs at 2.1 MHz - and the figures here are the X values: switching frequency of 595 kHz to 805 kHz (700 kHz typical), feedback reference of 0.747 V to 0.782 V (0.765 V typical), quiescent current of 28 µA typical, and peak switch current limit of 1200 mA typical and 1700 mA maximum, from a 4 V to 60 V input, delivering up to 600 mA. The selection point is 60 V input tolerance in a six-pin package: 24 V and 48 V industrial rails, automotive accessory supplies and surge-exposed front ends get a buck that survives the transients smaller regulators cannot. Selection advice: quote the X code explicitly - an LMR16006YDDCR on the same footprint switches three times faster, which changes the inductor choice, the EMI signature and the efficiency balance, so the two codes are not silent substitutes. Parameters verified against the TI LMR16006 datasheet (device comparison and electrical characteristics for the X variant).
