Product details

Display driver in a PDSO12 footprint

The Texas Instruments LM3553SD is a display driver in a PDSO12 package, designed for driving LED or similar display loads in a compact surface-mount layout. It is listed under Discrete Semiconductors, indicating a focused function as a single-channel or limited-channel driver rather than a multi-channel shift-register backlight controller.

It is ROHS3 Compliant, covering the full RoHS exemption list including lead in solder — no additional compliance documentation beyond the standard TI declaration is typically required for EU or UKCA markets.

Sourcing and availability

The Bulk package format means it ships in tube or tray quantities suitable for prototype runs or small-series production, not tape-and-reel for high-volume pick-and-place.

Frequently asked questions

What is the closest functional second-source to LM3553SD?

The TLC5940RHBR is a 16-channel constant-current LED driver with a shift-register topology, while the LM3553SD is a simpler display driver in a PDSO12 package. They are not pin-compatible or direct drop-in replacements — the TLC5940RHBR targets backlight applications with higher channel count and PWM dimming, so a board redesign would be required to swap between them.
