DESCRIPTION
The EVmEZDPD3603A-00A is an evaluation
board for the mEZDPD3603A, which provides an
I2C interface. The mEZDPD3603A has a 4.5V to
36V input voltage range, and an adjustable 0.6V
to 12V output voltage range (3.3V by default).
The EVmEZDPD3603A-00A has a continuous
3A of output current.
The mEZDPD3603A is a digital, DC/DC step-
down power supply with multiple-time
programmable (MTP) memory and a simple GUI
to configure the device. The GUI provides
flexible power management functions, such as
setting the output voltage, switching frequency,
output current limit, multiple protection modes,
and compensation.
For more details, refer to the mEZDPD3603A
datasheet. The mEZDPD3603A is available in a
standard DIP (16mmx23mmx6.5mm) package.

QUICK START GUIDE
1. Connect the load to:
a. Positive (+): VOUT
b. Negative (-): GND
2. Preset the power supply output to be between 4.5V and 36V, and then turn the power supply off.
3. Connect the power supply terminals to:
a. Positive (+): VIN
b. Negative (-): GND
4. Turn the power supply on. The board should automatically start up.
