MAX14713 Evaluation Kit

General Description

Quick Start

The MAX14713 evaluation kit (EV kit) is a fully assembled

and tested circuit board that demonstrates the MAX14713

power path selector. To evaluate the MAX14714, request

a sample from Maxim and replace the MAX14713 with

the MAX14714.

Required Equipment

●

MAX14713 EV kit

3V DC power supply

Two 5V DC power supplies

Multimeter

EV Kit Contents

● MAX14713 EV Kit Board

Procedure

The MAX14713 EV kit is fully assembled and tested.

Follow these steps to verify board operation:

Features

● 1.6V to 5.5V Operating Voltage Range

1) Verify that all jumpers are in their default positions.

2) Connect 3V DC supply to VIO. Turn on the power

supply.

3) Connect one 5V DC supply to IN1. Connect one 5V

DC supply to IN2.

● Proven PCB Layout

● Fully Assembled and Tested

4) Turn on IN1 supply. Verify LED1 is on and OUT is 5V.

5) Turn off IN1 supply. Verify LED1 is off.

6) Turn on IN2 supply. Verify LED1 is on and OUT is 5V.

7) Turn off IN2 supply. Verify LED1 is off.

8) Set IN1 to 4V and IN2 to 3.5V, and turn on both

power supplies. Verify OUT goes to 4V.

9) Increase IN2 to 4.1V. Note that OUT is still 4V.

10) Slowly increase IN2. Verify OUT = IN2 when IN2

reaches ~4.2V.

Ordering Information appears at end of data sheet.

11) After OUT = IN2. Decrease IN2 to 3.9V. Verify OUT =

IN2 still.

12) Slowly decrease IN2. Verify OUT = IN1(4V) when IN2

reaches ~3.8V.

Output Load

Detailed Description of Hardware

Use JU3, JU5, and JU7 to select output load. See Table 2

for jumper settings.

The MAX14713 EV kit is a fully assembled and tested circuit

board demonstrating the MAX14713 power path selector IC

in a 15-bump, surface-mount, wafer-level package (WLP).

VIO Power Source

Use JU6 to select the VIO power source. See Table 3 for

jumper settings.

The MAX14713 EV kit features an LED to indicate that

input is powered from either channel 1 or 2.

Enable Inputs

Use JU1 and JU2 to enable the device. See Table 1 for

jumper settings.

LED Indicator

Use JU8 to enable the LED indicator. See Table 4 for

jumper settings.
