The HR1001B is a noise-proofed, enhanced version of the HR1001, and it is pin-to-pin and BOM-to-BOM with the HR1001. The HR1001B is an enhanced LLC controller, which provides new adaptive dead-time adjustment (ADTA) and capacitive mode protection (CMP) features. Adaptive dead-time adjustment automatically inserts a dead time between the two complimentary gate outputs. This is ensured by keeping the outputs off while sensing the dV/dt current of the half-bridge switching node. The ADTA features easier design, lower EMI, and higher efficiency. The HR1001B incorporates anti-capacitive mode protection, which prevents potentially destructive capacitive mode switching if the output is shorted or has a severe overload. This feature protects the MOSFET during abnormal conditions, making the converter robust. The HR1001B has a programmable oscillator that sets both the maximum and minimum switching frequencies. It starts up at a programmed maximum switching frequency and decays until the control loop takes over to prevent excessive inrush current. The HR1001B enters a controlled burst mode at light-load to minimize the power consumption and tighten output regulation. The HR1001B provides rich protection features, including two-level OCP with external latch shutdown, auto-recovery, brown-in/out, CMP, and OTP, improving converter design safety with minimal external components.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
HR1001B 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 HR1001B datasheet above.
Electronic component spot-market pricing for HR1001B 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.
Lead times for HR1001B 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.
