The MP3373 is a step-up controller with 8-channel external current sources designed for driving the WLED arrays for large-sized LCD panel backlighting applications. The device employs peak current mode, fixed-frequency architecture to provide robust operation with 9V to 40V input supply. The switching frequency is programmable by an external frequency setting resistor. The MP3373 integrates a constant current control circuit to regulate each LED string current to the programmed value set by an external resistor. The current matching can achieve 1.2% regulation accuracy between strings. Its low 200mV regulation voltage on LED current sources reduces power loss and improves efficiency. To reduce inrush current and the stress of components, the MP3373 employs phase-shift PWM dimming mode, which can be disabled by pulling the PSEN pin to GND. The device also includes UVLO, LED short/open protection, inductor/diode short protection, and thermal shutdown protection. All fault statuses are indicated by the fault flag signal. The MP3373 is flexible for extending LED channels with two or three ICs in parallel, sharing one power stage. It is available in TSSOP-28 and SOIC-28 packages.

EV3373-M-00A is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Development Tools. 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 EV3373-M-00A datasheet above.
Electronic component spot-market pricing for EV3373-M-00A 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 EV3373-M-00A 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.
