At a 5 V output from a 3.3 V input, you'll get roughly 1.2 A continuous before the switch hits its cycle-by-cycle limit; derate further at higher output voltages because the duty cycle eats into the available switch on-time. The input range is 0.8 V minimum to 14 V maximum — it starts from a single alkaline cell (0.8 V is below the cutoff of a fresh NiMH) and runs all the way to a 12 V rail. The output is adjustable from a 1.24 V reference up to 14 V, set by an external resistor divider. No synchronous rectifier (external Schottky required), so the diode forward drop and switching losses eat into efficiency at higher switching frequencies. Switching frequency is programmable from 300 kHz to 2 MHz via an external resistor — pick 300 kHz for best efficiency (lower gate-drive losses) or 2 MHz to shrink the inductor and output capacitor at the cost of about 5-8% efficiency drop. ## Lifecycle and compliance — what the record says It's ROHS3 compliant, so it passes the latest EU RoHS exemption list (no lead, no halogens beyond trace limits). No REACH or UL certification is stated in this record, but TI typically provides a full material declaration on request. Because it's Active, you can source it through authorized distribution without a last-time-buy clock ticking.","metaTitle":"Texas Instruments LM2623AMM/NOPB Boost Regulator","metaDescription":"Texas Instruments LM2623AMM/NOPB step-up DC-DC converter, 0.8V-14V input, 2.2A switch, 300kHz-2MHz, adjustable output.
