The MP3366 is a step-up converter with 6-channel current sources designed to drive white LED arrays for backlighting in mid- to large-sized LCD panels. The MP3366 uses peak-current mode as its PWM control architecture. The switching frequency can be programmed by a resistor. The MP3366 generates an output voltage up to 45V from a 3V-to-25V input supply. The MP3366 regulates the current in each LED string independently to the value set by an external current-setting resistor. The MP3366 applies six internal current sources in each LED string terminal to achieve a current balance with 1.5% current regulation accuracy between strings. Its low 500mV regulation voltage on the LED current sources reduces power loss. The MP3366 features mixed digital PWM dimming and analog dimming with a 25% PWM duty cycle as a transfer point. The mix-dimming strategy helps to improve the dimming ratio. The MP3366 switches the PWM input signal from 100Hz to 20kHz to 23.5kHz to 29.5kHz automatically to eliminate audible noise. Full protection features include recoverable over-current protection (OCP), over-voltage protection (OVP), over-temperature protection (OTP), and short and open protection of any string on the LED. The MP3366 is available in a WLCSP-18(1.35mmx2.55mm) package.
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.
MP3366 is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Unclassified. 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 MP3366 datasheet above.
Electronic component spot-market pricing for MP3366 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 MP3366 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.

RTL8127-CG brings 10GbE to compact PCs, but the PCIe link, switch ports and cabling decide whether you see 10GbE end to end. YG GROUP sources the controller code your platform actually validated. Compare measured throughput with a 5GbE upgrade before selecting hardware, then confirm quantities and required dates.

STM32N657X0H3Q brings NPU acceleration to edge AI, but model size, external flash, RAM use and deployment tools decide whether a design fits. YG GROUP therefore quotes the MCU together with your approved memory BOM. Review those constraints before committing, then share exact order codes, quantities and target dates for a sourcing discussion.

In a BQ76952PFBR pack, the top cell can receive less average balancing current because measurements interrupt balancing, so configuration matters as much as the part. YG GROUP sources the full part number once settings are defined. Review configuration, timing and thermal limits for your LiFePO4 pack, then share cell count and quantities.

LTC4286AUK#PBF protects 48 V AI server boards during live insertion and reports power data over PMBus, but the external MOSFET's safe operating area decides survival. YG GROUP sources the controller for that validated power path. Examine inrush control, MOSFET SOA and Linux telemetry support, then specify the exact QFN variant, quantities and delivery dates.
