The MP3317 is a boost converter with 6-channel current sources designed to drive WLED arrays for LCD panels in virtual reality (VR) backlighting applications. The MP3317 uses peak current mode and pulse-width modulation (PWM) control to maintain boost converter regulation. The integrated 6-channels of the LED current source support a maximum 160mA/channel with 2.5% LED current (ILEDx, where x = 1–6) accuracy, and 2% matching accuracy. The device supports direct PWM dimming for the left and right LCD panels through two PWM dimming signal input pins (PWML and PWMR). The MP3317 features high efficiency due to a low headroom voltage for LED regulation, and the switching MOSFET has a small on resistance (RDS(ON)). The MP3317 employs a standard, I2C digital interface to set the operation mode, switching frequency (fSW), channel enable, LED current amplitude, cycle-by-cycle current limit, input current limit, and various protection thresholds. For system reliability, the MP3317 integrates rich protections, including open LED protection, short LED protection, short LEDx-to-GND protection, cycle-by-cycle over-current protection (OCP_CBC), input over-current protection (OCP_IN), latch-off over-current protection (OCLATCH), ISET short protection, ISET open protection, over-voltage protection (OVP), and over-temperature protection. The MP3317 is available in a WLCSP-20 (1.75mmx2.45mm) 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.
MP3317 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 MP3317 datasheet above.
Electronic component spot-market pricing for MP3317 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 MP3317 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.
