That switch current is the peak current the inductor sees, not the continuous output current — the actual output current you can deliver depends on the input-to-output voltage ratio and the switching frequency. At a 3.3 V input boosting to 5 V, the 2.2 A switch supports roughly 1.2 A output; at a higher step-up ratio from a single-cell Li-ion (3.0 V to 12 V), the output current drops to about 500 mA. The converter operates from a minimum input of 0.8 V, which means it can start up from a nearly depleted alkaline cell or a single NiMH battery. The maximum input and output voltage is 14 V, so the part suits battery-powered equipment, portable instruments, and low-voltage sensor nodes that need a regulated higher rail. Switching frequency is programmable from 300 kHz to 2 MHz via an external resistor. A higher frequency shrinks the inductor footprint (smaller value, smaller core) but increases switching losses; a lower frequency improves efficiency at light loads. The 2 MHz ceiling keeps the fundamental switching noise above the AM radio band, which matters for noise-sensitive portable gear. ## Non-synchronous rectification — the external diode is part of the BOM The LM2623MM/NOPB uses a non-synchronous rectifier topology, meaning the output diode is external. This adds a Schottky diode to the BOM (typically a 1 A, 20 V part) but keeps the controller simple and the quiescent current low. The trade-off is slightly lower efficiency at high output currents compared to a synchronous boost, but the external diode lets you optimise the forward voltage drop for your specific output voltage and load range. ## Package and temperature grade for production planning The device is offered in an 8-MSOP (0.118\" wide, 3.00 mm) package, also listed as the supplier device package 8-VSSOP. The 0.65 mm pin pitch is standard for this footprint family and routes easily on a two-layer board. Packaging options include Tape & Reel (TR) for automated pick-and-place in volume production and Cut Tape (CT) for prototype or low-volume builds. The RoHS3 compliance covers the EU RoHS exemption list through 2024, so the part is acceptable for new designs shipping into Europe without a waiver. ## Active lifecycle — no end-of-life pressure on this BOM line No stock-holding claim is made; the sourcing posture is per-quote.","metaTitle":"Texas Instruments LM2623MM/NOPB Boost Regulator, 2.2A Switch","metaDescription":"Texas Instruments LM2623MM/NOPB step-up DC-DC converter. 2.2A switch, 0.8V-14V input, adjustable output to 14V.
