RISEIC — Hong Kong Chenshengwei Electronics

Power Management ICs

Power management touches every board, and shortages here stop whole production lines. We stock 21,000+ power IC part numbers: switching regulators and controllers, LDOs, PMICs, DDR memory terminators, gate drivers, supervisors and battery management.

TI TPS and LM lines, ST L78/L79 and VIPER, Infineon TLE, onsemi NCP and legacy Linear Technology (ADI) regulators are all live stock lines with same-day quoting.

Coverage by function

Step-down (buck) converters and controllers, boost and buck-boost, LDOs from 150 mA to 3 A, multi-rail PMICs for processors and FPGAs, DDR VTT terminators such as the TPS51116 family, high/low-side gate drivers, voltage supervisors and reset ICs.

For automotive power (Infineon TLE, AEC-Q qualified LDOs and pre-regulators) we supply PPAP-aligned documentation and lot traceability on request.

Why buyers use us for power ICs

Franchise lead times on popular regulators have repeatedly stretched past 26 weeks. We hold buffer stock on high-runners and can usually ship production quantities inside a week.

Mixed-lot consolidation is standard: combine power ICs with the rest of your BOM in one shipment, one invoice, one customs entry.

Frequently Asked Questions

Can you supply AEC-Q automotive power ICs?

Yes — TLE and AEC-Q qualified regulators ship with lot traceability and documentation on request.

What lead time do you offer on TI TPS parts?

Stocked lines ship in 1–3 days; non-stocked lines are quoted with a firm market lead time.

Do you break reels for samples?

Yes, cut-tape samples from one piece are available on most SMD lines.

Can you consolidate power ICs with my BOM?

Yes, single-shipment BOM consolidation is our standard service.

Are parts new and original?

Yes — new, original factory packing with date codes stated on the quote.
