The MP3383 is a step-up controller with four LED current channels, designed to drive WLED arrays for large LCD panel backlighting applications. The MP3383 can expand the number of LED channels with two or more ICs in parallel sharing a single power source. The MP3383 employs peak current control mode with a fixed switching frequency (fSW) that is configurable via an external setting resistor. The MP3383 drives an external MOSFET to boost up the output voltage (VOUT) from a 6V to 33V input voltage (VIN) supply. It also regulates the current in each LED string to the value set by an external current-setting resistor. The MP3383 applies four internal current sources for current balancing. The current matching achieves 1.8% regulation accuracy among strings. The low regulation voltage on the LED current sources reduces power loss. The MP3383 supports direct pulse-width modulation (PWM) dimming and analog dimming via a PWM input. Full protection features include over-current protection (OCP), over-temperature protection (OTP), under-voltage protection (UVP), over-voltage protection (OVP), LED short protection, LED open protection, inductor short protection, and diode short protection. The MP3383 is available in SOIC-16 and TSSOP-16EP packages.
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.
MP3383 is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Driver 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 MP3383 datasheet above.
Electronic component spot-market pricing for MP3383 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 MP3383 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.
