LM5122QMHX/NOPB

LM5122QMHX/NOPB is the tape-and-reel HTSSOP-20 (PWP) ordering code for the Texas Instruments LM5122-Q1 synchronous boost controller, listed by TI as ACTIVE on the part-details page for this exact variant. The family is AEC-Q100 qualified at device temperature grade 1 (-40 °C to +125 °C ambient), with HBM ESD level 2 and CDM ESD level C6 stated on the TI product page. The controller runs from a 3 V to 65 V input (4.5 V needed at start-up), can regulate outputs up to 100 V against a 1.2 V ±1 % reference, synchronises up to 1 MHz, drives gates at 3 A, draws 9 µA in shutdown and 4 mA typical operating current, and supports a 100 % duty-cycle bypass mode. The selection point is automotive boost stages that outgrow integrated switches: front-end supplies and start-stop tolerant rails get an external-MOSFET controller with documented automotive qualification. Selection advice: quote the /NOPB suffix in full and confirm the MHX reel code against the MH tube code - the lifecycle and packing statements verified here are for this exact suffixed variant. Parameters verified against the TI LM5122-Q1 product page and the part-details page for LM5122QMHX/NOPB.
