The MP3398E is a step-up controller with four current channels designed to drive WLED arrays for large-size LCD panel backlighting applications. The MP3398E is able to expand the number of LED channels with two or more ICs in parallel sharing a single power source. It employs peak current mode with a fixed switching frequency. The frequency is programmable through an external setting resistor. The MP3398E drives an external MOSFET to boost up the output voltage from a 4.5V to 33V input supply, and regulates the current in each LED string to the value set by an external current-setting resistor. The deviceapplies four internal current sources for current balancing. The current matching achieves 2.3% regulation accuracy between strings. The low-regulation voltage on the LED current sources reduces power loss. The MP3398E supports direct PWM dimming and analog dimming with PWM input. Full protection features include over-current protection (OCP), over-temperature protection (OTP), under-voltage protection (UVP), over-voltage protection (OVP), LED short/open protection, and inductor/diode short protection. The MP3398E is available in TSSOP-16EP and PDIP-16 packages.

EV3398E-U-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 EV3398E-U-00A datasheet above.
Electronic component spot-market pricing for EV3398E-U-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 EV3398E-U-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.
