Product details

Temperature range and environment

Rated for junction temperatures from -40°C to 125°C, this part handles outdoor telecom enclosures, automotive cabin lighting, or industrial panel backlights where the ambient can climb. The wide range also covers cold-crank battery conditions in portable equipment.

Active lifecycle — no LTB watch needed

The LM2703MF-ADJ/NOPB carries an Active product status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect. It remains a safe choice for new designs and production BOMs without near-term obsolescence risk.

Frequently asked questions

What is the maximum output current of LM2703MF-ADJ/NOPB?

The internal switch is rated for 350 mA peak current. The actual LED current depends on the boost topology and external components; for typical backlight strings at 20 mA per LED, the part has ample headroom.

Can LM2703MF-ADJ/NOPB drive multiple LEDs in series?

Yes. With a 21V output ceiling, it can drive up to five or six white LEDs in series (typical forward voltage ~3.2V each), which is the standard configuration for small-to-medium LCD backlights.
