• Manufacturer Part Number: MAX1577ZEVKIT
• Description: Charge Pumps Evaluation Kit for the MAX1577Y MAX1577Z
• Manufacturer: Maxim Integrated

Specifications of MAX1577ZEVKIT

• Function: Step Up, Step Down
• Output Voltage: 3.4 V, 4.6 V, 5.1 V
• Output Current: 1200 mA

When using the on-board pulse generator, the LED
flashes when power is first applied to the EV kit. This is
due to the pulse generator circuit and not the MAX1577Z.
To use external pulse generators, remove the shunts
from both JU1 and JU2, and connect the pulse genera-
tors to the pads labeled EN1 and EN2. For a simple
flash at 100% brightness, connect EN1 to EN2 and
drive with a single pulse generator.
To place the MAX1577Z in low-power shutdown mode,
remove the shunt from both jumpers JU1 and JU2. For
measuring quiescent current while in shutdown mode,
also remove the shunt from JU3 to disconnect the on-
board pulse generator from the supply.
To connect external LED(s) to the MAX1577Z EV kit, cut
the trace shorting JU4. Connect the anode(s) of the
external LED(s) to the pad labeled LED+. Connect the
cathode(s) to the pad labeled GND.
Note: Indicate that you are using the MAX1577Y/MAX1577Z when contacting these component suppliers.

To evaluate the MAX1577Y, carefully remove the
MAX1577Z from the EV kit and replace with the
MAX1577Y. Free samples of the MAX1577Y are available
from Maxim.
To evaluate the voltage regulation settings of the
MAX1577Y, follow the procedure in the
Regulation section.
The MAX1577Y/MAX1577Z can provide a constant volt-
age output. In voltage-regulation mode, the MAX1577Z
has a fixed 5.1V output. The output voltage of the
MAX1577Y is selected using JU1 and JU2. Refer to the
MAX1577Y/MAX1577Z data sheet for more information.
To configure the MAX1577Z EV kit for voltage regula-
tion, cut the trace shorting JU4. Connect the load from
the pad labeled OUT to the pad labeled GND.
