EVM3606A-QV-00A
21V/0.6A Module Converter with
Integrated Inductor Evaluation Board
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The EVM3606A-QV-00A is an evaluation board
for MPM3606A, a synchronous rectified, stepdown module converter with built-in power
MOSFETs, inductor and two capacitors.
•
•
The evaluation board can deliver a 0.6A
continuous output current with excellent load
and line regulation over a wide input supply
range.
Current-mode operation provides fast transient
response and eases loop stabilization.
Full protection features include over-current
protection and thermal shut down.
The MPM3606A is available in a space-saving
QFN20 (3mm x5mmx1.6mm) package.

QUICK START GUIDE
1. Connect the positive and negative terminals of the load to the VOUT and GND pins, respectively.
2. Preset the power supply output between 4.5V and 21V, and then turn off the power supply.
3. Connect the positive and negative terminals of the power supply output to the VIN and GND pins,
respectively.
4. Turn the power supply on. The board will automatically start up.
5. To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 1.4V to turn
on the converter, or less than 1.25V to turn it off.
