MAX1830 Evaluation Kit

General Description

Features

The MAX1830 evaluation kit (EV kit) provides a 1.8V

output from a 3V to 5.5V input voltage source. It deliv-

ers up to 3A output current with a 94% (max) efficiency.

The MAX1830 EV kit includes the MAX1830 step-down

switching regulator with an internal synchronous rectifi-

er to increase efficiency and reduce the number of

external components. The resistor-programmable fixed-

off-time, current-mode architecture allows an optimum

response to load and line transients. This EV kit, as

configured, operates at approximately 550kHz from

3.3V inputs and 770kHz from 5V inputs.

The MAX1830 EV kit can be configured to produce a

preset output voltage of 1.5V, 1.8V, 2.5V, or is feedback

adjustable from 1.1V to V .

This EV kit can also be used to evaluate the MAX1831

with preset output voltages of 1.5V/1.8V and 3.3V, or

ꢀ Fully Assembled and Tested

adjustable output voltage from 1.1V to V .

Quick Start

Schottky diode

(not installed)

The MAX1830 EV kit is a fully assembled and tested

surface-mount board. Follow the steps below for proper

board operation. Do not turn on the power supply

until all connections are completed:

1.5µH inductor

Sumida CDRH6D28–4762T064

1) Connect a voltmeter and load (if any) from VOUT to

GND.

5% resistor (0603)

1% resistor (0805)

2) Verify that there is a shunt on JU1 (shutdown dis-

abled).

84.5k

Not installed (0805)

MAX1830EEE (16-pin QSOP)

2-pin header

3) Verify that the JU2 shunt is connected across pins

1 and 4 to set the output to 1.8V.

4) Connect a 3V to 5.5V supply to the pads marked

VIN and GND (supply off).

JU1

JU2

4-pin header

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

voltage is 1.8V.

Not installed (shorted with PC board

trace)

JU3

6) See the Output Voltage Selection section to modify

the board for a different output voltage.

None
