GENERAL DESCRIPTION
FEATURES
The EV2364/1541-00A is an evaluation board
for DSL Power applications. It has four outputs
and can supply 1.5A continuous output current
over a wide input supply range with excellent
load and line regulation. Current mode
operation provides fast transient response and
eases loop stabilization. Fault condition
protection includes cycle-by-cycle current
limiting and thermal shutdown.

QUICK START GUIDE
The output voltages of this board are set to 3.3V (VOUTA), 1.8V (VOUTB), 12.8V (VOUTC) and 5V
(VOUTD). The board layout accommodates most commonly used inductors and output capacitors.
1. Attach the positive and negative ends of the first load to the VOUTA and GND pins,
respectively. If using other outputs, attach the positive and negative ends of their loads to the
respective VOUT and GND pins for the desired outputs.
2. Preset the power supply output to 5V to 23V and turn it off.
3. Connect the positive terminal of the power supply output to the VIN pin and the negative
terminal of the to the GND pin.
4. Turn on the power supply. The EV2364DF/1541DJ will automatically startup.
5. To use the Enable function, apply a digital input to the ENA/ENB pins. Drive EN higher than
2.5V to turn on the regulator and less than 0.7V to turn it off.
