PWM dimming input controls brightness, and the 1.3 MHz switching frequency allows small external components. It accepts a 5 V to 24 V supply rail.
No LTB window to track, no forced redesign on the horizon — it is safe to qualify into a production BOM.
The maximum output voltage of 38 V allows roughly ten white LEDs in series per string, depending on forward voltage.
The LM2703MF-ADJ/NOPB is a single-output boost LED driver with a 0.35 A output current and a wider temperature range (-40°C to 125°C). It is not a pin-for-pin replacement — it has one output versus six, and its package differs. For a six-channel part, the TPS61182RTER is the correct choice.
