Power & Analog

Power conversion and signal chain, priced properly.

Regulators, converters, MOSFETs, op-amps and drivers — the parts that decide whether a design hits its BOM target. Many are commodity devices where the price difference between channels is large, and a few are quietly obsolete. Both are our business.

Examples only — the power and analog market carries thousands of near-equivalent devices. Send your exact part number, or describe the function (input range, output, current) and we will propose specific options with pricing.

Practical things worth knowing
  • Equivalent parts are usually fine here. Unlike memory, power and analog devices are often interchangeable across pin-compatible families — this is where cost can be genuinely reduced.
  • Beware grey-market reclaims on popular MOSFETs. High-volume devices are the most counterfeited category in the market; buy these from traceable channels.
  • Consolidate passives with the ICs. Half the value of a power order is the surrounding resistors and capacitors — put them on the same list.
  • Datasheet matching is worth the extra day. We check the specific suffix: current rating, drop-out voltage and thermal package all differ between variants that share a base part number.
What to send us
  • Exact part number with suffix, or a functional description if you are still choosing.
  • Quantity and target unit price.
  • Whether pin-compatible equivalents are acceptable, and any brand restriction from your end customer.
  • Traceability requirements for high-volume or high-value lines.
  • Test or screening requirements, if the application is automotive, medical or high-reliability.
