Product Details
Key Features
Documentation

The MP161 integrates a 700V switching regulator, a low-dropout linear regulator, and two channel relay drivers. The MP161 also has a special standby mode to minimize standby power. The MP161 is designed for home automation, industrial automation, and any other applications that adopt relays and MCUs. The 700V switching regulator adopts constant voltage (CV) regulation with internal loop compensation. Light-load efficiency is optimized by proper modulation of the switching frequency and peak current. Various protections are also included to guarantee reliable operation. The integrated low-dropout linear regulator is able to operate with an input up to 30V. The output voltage is fixed at either 5V or 3.3V. The MP161 also has over-temperature protection (OTP). Built-in relay drivers are intended to drive up to two relays using the switching regulator output. Freewheeling diodes are integrated to cut down external components. When standby mode enabled, the switching regulator output voltage is lowered to reduce power consumption. The MP161 is available in a SOIC-16 package.

YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is MP161B, and what package does it use?

MP161B is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official MP161B datasheet above.

Why is pricing for MP161B available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for MP161B fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.

How quickly can MP161B be shipped once quoted?

Lead times for MP161B depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
