The MP3385B is a step-up controller with four regulated LED current (ILED) channels, designed to drive white LED (WLED) arrays for mid-sized and large-sized LCD panel backlighting applications. The MP3385B employs peak current control mode and pulse-width modulation (PWM) control architecture for system loop regulation. It drives an external MOSFET to boost the output voltage (VOUT) from a 4.5V to 33V input voltage (VIN) supply. The MP3385B provides an I2C digital interface to flexibly set the operation and protection modes, including dimming mode, the dimming current, the dimming ratio, over-current protection (OCP), over-voltage protection (OVP), the LED short protection threshold, and the switching frequency (fSW). For ease of use and board debugging, the MP3385B automatically detects and disables the unused LED strings during start-up to avoid charging the output to the OVP threshold. The device achieves 1.8% current matching between each string. The low regulation voltage on the LED current source improves efficiency and reduces power loss, which can result in a higher current output. The MP3385B supports analog, PWM, and combined analog and PWM dimming modes to meet different application requirements. Full protection features include OCP, over-temperature protection (OTP), under-voltage protection (UVP), OVP, LED short and open protection, and inductor and diode short protection. The MP3385B is available in a QFN-20 (4mmx4mm) 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.
MP3385BGR 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 MP3385BGR datasheet above.
Electronic component spot-market pricing for MP3385BGR 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 MP3385BGR 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.
