Monolithic Power Systems Inc. EV2016DD-00A

Overview

EV2016DD-00A from Monolithic Power Systems is an evaluation board for the MP2016DD low-power linear regulator IC, designed to demonstrate high-voltage (7–42V input), adjustable-output (1.2–24V) regulation in battery-powered systems. It delivers 5V at up to 30mA with ±2% output accuracy, 50dB PSRR, and 12µA quiescent current, validated on a 5.1cm × 5.1cm QFN-8-based layout.

For engineers reviewing the EV2016DD-00A datasheet, EV2016DD-00A pinout, EV2016DD-00A application, or EV2016DD-00A equivalent, this board enables rapid validation of MP2016DD performance under line/load transients, thermal shutdown behavior, and resistor-divider-based output programming in handheld and smart-battery applications.

Technical Context

The EV2016DD-00A implements the MP2016DD IC in a fixed 5V configuration using a precision 24.9kΩ (R2) and 76.8kΩ (R1) feedback divider, targeting V_FB = 1.23V. Input filtering uses 1µF and 4.7µF X7R ceramic capacitors (1206), while a 22nF bypass capacitor (603) stabilizes the feedback node.

Board-level functionality includes automatic startup via 100kΩ pull-up from SHDN to VIN, manual disable by grounding SHDN, and direct access to all eight pins (IN, OUT, GND, FB, SHDN, and three NC terminals) for probing and reconfiguration - matching the QFN-8 package pinout of the MP2016DD.

FAQ

What is the default output voltage and how is it set?

The EV2016DD-00A is configured for 5.00 V output using R1 = 76.8kΩ and R2 = 24.9kΩ, based on the MP2016DD's 1.23 V feedback threshold. This ratio satisfies V_OUT = 1.23V × (1 + R1/R2), yielding 5.00 V within ±2% tolerance per datasheet specification.

Can the output voltage be adjusted, and what components must be changed?

Yes - replace R1 and R2 with values satisfying V_OUT = 1.23V × (1 + R1/R2). R2 must remain a 1% tolerance 24.9kΩ resistor per design guide; R1 is calculated accordingly. The board provides solder pads and silkscreen labels for both resistors, supporting 1.2–24V output range validation.

How is enable/disable functionality implemented on this board?

The SHDN pin is pulled high to VIN through a 100kΩ resistor (R3), enabling automatic startup when input is applied. To disable the regulator, connect SHDN directly to GND - a test point and header pin are provided for this purpose, confirming active-low enable logic per MP2016DD specification.

What input capacitance is used, and why is it specified as 1µF + 4.7µF?

C1 (1µF, 50V X7R, 1206) handles high-frequency noise; C2 (4.7µF, 25V X7R, 1206) supplies bulk charge during load transients. This dual-capacitor strategy ensures stability across 10Hz–1MHz, meeting MP2016DD's input ESR and capacitance requirements for dropout and PSRR performance.

Does the board expose all MP2016DD pins, and which are unused?

Yes - all eight QFN-8 pins are routed to test points or headers: IN, OUT, GND (×3), FB, SHDN, and three NC terminals (pins 2, 3, 6 per schematic). NC pins are unconnected but accessible for probing or future modification, preserving full IC signal visibility without solder bridging.
