Product details

Boost LED driver in a 1.22x1.62 mm DSBGA

The LM3530UMX-40/NOPB: The integrated switch and PWM dimming input simplify the bill of materials for small-panel backlight drivers in portable equipment.

12-bump DSBGA — what the board needs

Housed in a 12-XFBGA (1.22x1.62 mm body, 0.4 mm pitch typical), the LM3530UMX-40/NOPB demands a controlled board-level assembly process — the supplier device package is 12-DSBGA. The small footprint favours dense layouts but requires careful solder-paste stencil design and X-ray inspection for voiding under the bumps.

Active lifecycle, no PCN watch needed

ROHS3 compliant per, with no REACH or conflict-minerals restrictions flagged in this listing.

Frequently asked questions

What is the LM3530UMX-40/NOPB's topology and output voltage?

It is a step-up (boost) DC-DC regulator with a maximum output of 40 V, switching at 500 kHz.

Is the LM3530UMX-40/NOPB a direct replacement for the TLC5940RHBR?

No — the TLC5940RHBR is a 16-channel linear shift-register LED driver with 0.12 A per channel, while the LM3530UMX-40/NOPB is a single-channel boost regulator. The topology, output count, and package (12-DSBGA vs 32-QFN) differ, so a board spin is required.

What dimming method does the LM3530UMX-40/NOPB support?

PWM dimming is supported directly on the control pin, allowing external PWM signal control of LED brightness.
