MAX1837 Evaluation Kit

General Description

Features

ꢀ Preset +3.3V Output Voltage

The MAX1837 evaluation kit (EV kit) is a fully assembled

and tested surface-mount circuit board that demon-

strates the performance of the MAX1837 step-down

DC-DC converter. The EV kit provides a +3.3V output

from a +4.5V to +24.0V input and can deliver up to

250mA of load current. The EV kit circuit includes the

MAX1837EUT33 DC-DC converter, which is preset to

regulate the output voltage to +3.3V but can be recon-

figured to output voltages in the +1.25V to +5.5V

range. This EV kit can also be used to evaluate other

preset voltage parts in the MAX1836/ MAX1837 family.

ꢀ 250mA Output Current

ꢀ +4.5V to +24.0V Input Voltage Range

ꢀ Adjustable Output Voltages (+1.25 to +5.5V)

ꢀ Low 12µA (typ) Quiescent Supply Current

ꢀ Surface-Mount Construction

ꢀ Fully Assembled and Tested

The MAX1837 EV kit is a fully assembled and tested

surface-mount board. Follow the steps below for board

operation. Do not turn on the power supply until all

connections are completed:

1) Verify that a shunt is connected across pins 1 and 2

of jumper JU1.

2) Connect a voltmeter across the VOUT and GND

pads to monitor output voltage.

3) Connect a +4.5V to +24.0V supply to the VIN pad.

Connect the ground terminal to the GND pad.

4) Turn on the power supply and verify that the output

voltage is +3.3V.
