Overview

Supplier sourcing insights & recommendations

I have identified the IC chip with the marking "S21B" as the LM3488 High-Side N-Channel Controller manufactured by Texas Instruments.

The market for this chip in 2026 is characterized by a "repricing wave," with prices for analog ICs and power management components increasing by 10–30% due to sustained demand from the automotive and AI infrastructure sectors. Major suppliers like TI have already implemented broad price hikes, and securing stock for unpriced orders early is highly recommended to mitigate rising procurement costs.

I have found several verified suppliers with the LM3488MM (S21B) in stock, many of whom offer comprehensive BOM sourcing services. You can find the full analysis of technical specifications, current price trends, and the detailed list of vetted suppliers in the report provided below.

I've prepared the full market and supplier report for the LM3488 IC chip. You can explore further with:
