The HF500-40 is a fixed-frequency, current-mode regulator with built-in slope compensation. The HF500-40 combines a 700V MOSFET and a full-featured controller into one chip for a low-power, offline, flyback, switch-mode power supply. At medium and heavy loads, the regulator works in a fixed frequency with frequency jittering. Jittering helps reduce EMI energy on the switching frequency and its harmonics. During light-load condition, the regulator freezes the peak current and reduces its switching frequency to 25kHz to offer excellent efficiency. At very light loads, the regulator enters burst mode to achieve low standby power consumption. Full protection features include brown-in and brown-out, VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), input over-voltage protection (OVP), VCC over-voltage protection (OVP), and over-temperature protection (OTP). The HF500-40 features over-power line compensation to ensure that the overload protection point is independent of the input voltage. The HF500-40 is available in a PDIP8-7B package. Advantages Include: Fully featured controller in one chip for a low-power, offline, flyback, switch-mode power supply Multi-mode control during different load conditions Over-power line compensation and full suite of protection features
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.
HF500GP-40 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 HF500GP-40 datasheet above.
Electronic component spot-market pricing for HF500GP-40 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 HF500GP-40 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.
