Monolithic Power Systems Inc. EV6001DN-00D

Overview

EV6001DN-00D from Monolithic Power Systems is a WLED driver evaluation board built around the MP6001DN IC, designed to drive six independent 20mA white LED strings with up to 10 LEDs per string, featuring PWM dimming, enable control, open-circuit voltage protection, and tight current balance across strings for LCD panel backlighting applications.

For engineers reviewing the EV6001DN-00D datasheet, EV6001DN-00D pinout, EV6001DN-00D application, or EV6001DN-00D equivalent, this board enables rapid validation of MP6001DN-based WLED driver designs under real-world input (7–21V), output (33V max), and thermal conditions on a compact 6.5cm × 1.5cm layout with documented test points and dual-board interconnect.

Technical Context

The EV6001DN-00D implements a boost-type DC-DC converter topology using the MP6001DN IC, which integrates a 150V power switch and 100V startup circuit. It supports cycle-by-cycle current limiting and delivers regulated constant current to six parallel LED strings via dedicated output terminals (S0–S5).

Board-level features include EN and DIM signal interfaces compatible with TTL/CMOS logic levels, open-circuit protection triggered at ~33V output, and efficiency optimization across 7–25V input range-peaking near 85% at 15V input with 20mA per string load.

FAQ

What is the purpose of the EV6001DN-00D evaluation board?

The EV6001DN-00D is a functional demonstration and development platform for the MP6001DN WLED driver IC. It allows engineers to validate performance-including current regulation accuracy, PWM dimming response, open-circuit protection behavior, and thermal stability-under real operating conditions before committing to custom PCB design.

How do I connect the LED board to the EV6001DN-00D driver board?

Connect CN1 (8-pin header) on the EV6001DN-00D to CN1 (8-pin header) on the companion LED board using a 2mm-pitch ribbon cable or mating headers. Pin mapping follows the schematic: S0–S5 and GND are routed directly; VIN and EN/DIM signals are shared via CN2 (4-pin header) as specified in the Quick Start Guide.

What input voltage range is supported, and how does efficiency vary?

The board operates from 7 V to 21 V DC input. Efficiency peaks near 85% at 15 V input with full 6-string 20mA load, dropping to ~70% at 7 V and ~75% at 21 V, as confirmed by the published efficiency vs. input voltage curve in the reference document.

Does the board provide test points for measuring individual string currents?

Yes-TP1 through TP18 are labeled test points on both boards. TP1–TP6 correspond to S0–S5 outputs and GND, enabling direct current measurement per string using a series resistor or clamp meter; TP7–TP18 map to LED anodes/cathodes on the LED board for per-LED verification.

Can the EV6001DN-00D be used with non-Monolithic LED driver ICs?

No-the board is specifically designed for and populated with the MP6001DN IC (U1). Its layout, component values, feedback network (R5–R7), and protection circuitry (ZD1–ZD4, Q1–Q5) are optimized for that device and not interoperable with other WLED drivers without redesign.

Is the board RoHS-compliant and lead-free?

Yes-the bill of materials lists only RoHS-compliant components (e.g., TDK C3225X7R1E106M, Panasonic ERJ-3GEYJ103V), and MPS documentation confirms the MP6001DN IC and associated evaluation hardware meet JEDEC J-STD-020 and RoHS Directive 2011/65/EU requirements.
