Monolithic Power Systems Inc. EV6001DN-01C

Overview

EV6001DN-01C from Monolithic Power Systems is an evaluation board for the MP6001 monolithic buck DC-DC converter IC, designed to validate 12 V @ 1.5 A output operation under 43–53 V input. It integrates cycle-by-cycle current limiting, thermal shutdown, and over-voltage protection, and supports zero-load regulation via cycle skipping. Used for telecom power subsystem validation.

For engineers reviewing the EV6001DN-01C datasheet, EV6001DN-01C pinout, EV6001DN-01C application, or EV6001DN-01C equivalent, this board enables rapid functional verification of MP6001-based 18 W isolated/non-isolated flyback/forward DC-DC designs in PoE-powered equipment and distributed telecom supplies.

Technical Context

The EV6001DN-01C implements a fixed-frequency (typ. 275 kHz) buck-derived forward topology using the MP6001 controller IC, which integrates a 150 V power switch and 100 V startup circuit. Input UVLO triggers at 40 V with hysteresis, and line feed-forward adjusts duty cycle across 43–53 V input range.

Board-level protections include auto-retry on over-current or short-circuit events, over-voltage latch-off at >13.2 V, and thermal shutdown at 150 °C. Efficiency reaches 90% at 48 V input / 1.2 A load, per measured data.

Manufacturer

Monolithic Power Systems (MPS) is a fabless analog semiconductor company specializing in high-efficiency power management ICs, founded in 1997 and headquartered in San Jose, California.

The MP6001 product line delivers high-voltage monolithic DC-DC controllers for telecom, industrial, and PoE applications where input voltages exceed 40 V and robust protection is required.

FAQ

What input voltage range is supported by the EV6001DN-01C?

The board accepts 43–53 V DC input, aligned with standard telecom rectified line and IEEE 802.3af/at PoE midspan outputs. Input UVLO activates below ~40 V, and over-voltage protection engages above 56 V, per MP6001 internal circuitry.

Can the output voltage be adjusted, and how?

Yes - output voltage is set by the R4/R7 resistor divider network on the feedback pin (FB) of U1 (MP6001). Replacing R4 (100 kΩ) or R7 (4.99 kΩ) changes the 12 V regulation point per the MP6001 datasheet's VOUT = 0.8 V × (1 + R4/R7) equation.

Does the board support enable/disable control, and what are the logic thresholds?

Yes - the EN pin accepts 2.5–5 V to enable regulation and <0.7 V to disable it. During startup, EN may be left unconnected (pulled high internally), and the pin is compatible with standard CMOS/TTL logic levels.

What protection features are implemented on this evaluation board?

The board inherits all MP6001 protections: cycle-by-cycle current limiting, thermal shutdown at 150 °C, over-voltage lockout (>13.2 V), input UVLO (~40 V), and auto-retry after over-current or short-circuit faults - all verified in the Rev 1.0 test report.

Is the EV6001DN-01C suitable for flyback or forward topology evaluation?

Yes - though based on a buck-derived controller, the MP6001 supports both flyback and forward topologies via external transformer and snubber design. The board's schematic and layout (Rev 1.0, p.3) confirm forward-mode implementation with D1 as output rectifier and L1 as output filter inductor.

What is the maximum output power and at what conditions is it rated?

Maximum output power is 18 W, achieved at 12 V × 1.5 A. This rating assumes 48 V input, ambient temperature ≤40 °C, and proper heatsinking of the MP6001 SOIC-8 exposed pad - consistent with the "up to 18W" specification in the General Description.
