Active production — 1A switch boost in a SOT-23-5
The LMR64010XMF/NOPB: Rated for a 1A switch current limit, the part delivers an adjustable output up to 40V from an input range of 2.7V to 14V — the 1A ceiling is the hard constraint for output power; at 5V in and 12V out, the maximum load current before hitting the switch limit is roughly 350 mA, assuming 85% efficiency.
Temperature grade and package — industrial range, rework-friendly footprint
No synchronous rectifier on-chip — an external Schottky diode (e.g., 40V, 1A rated) is required between the switch pin and output; the diode's forward drop directly subtracts from efficiency, so a low-VF Schottky like the BAT54 or MBR0540 is the standard pairing.
