EVM3610-QV-00A
21V/1.2A Mini-Module Regulator with
Integrated Inductor Evaluation Board
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The EVM3610-QV-00A is an evaluation board
for MPM3610, a synchronous rectified, stepdown Mini-Module regulator with built-in power
MOSFETs, inductor and two capacitors.
•
•
•
•
•
•
The evaluation board can deliver a 1.2A
continuous output current with excellent load
and line regulation over a wide input supply
range. External AAM pin provides selectable
power save mode or force PWM mode.
Full protection features include over-current
protection and thermal shut down.
The MPM3610 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 regulator, or less than 1.25V to turn it off.
6. Float AAM pin or drive AAM to a high level voltage to set MPM3610 work at force PWM mode.
