MAX20333 Evaluation Kit

General Description

Quick Start

The MAX20333 evaluation kit (EV kit) is a fully assembled

and tested circuit board that demonstrates the MAX20333

0.2A to 4.75A adjustable current-limit switch device. The

EV kit comes with the MAX20333ENL+ installed. The EV

kit board can also be used to evaluate MAX20333A/B/C/D/

E/F/G/H/I/J/K/L/M/N.

Required Equipment

● MAX20333 EV kit

● 9V Power Supply

● 5V Power Supply

● Multimeter

● Load Box

Features

● 3.5V to 22V Operating Voltage Range

Procedure

(3.3V to 22V for MAX20333L/M/N)

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation:

● Output and Flag LED Reading

● Adjustable Current Limit Setting

● Adjustable Blanking Time (PBT version)

● Proven PCB Layout

1) Connect 5V on V TP14.

2) Connect 9V on INPUT TP5. Use the voltmeter to

check that the OUT TP6 voltage is 9V.

3) Connect the load box to OUT. Increase the load

current and verify that the OUT voltage goes down

when output current goes up to about 1A, and D3

turns on (when overcurrent is in normal mode, FLAG

is asserted).

● Fully Assembled and Tested

EV Kit Contents

● EV Kit Board Containing a MAX20333ENL+

4) Remove the output load. Cycle the INPUT power,

verify D3 is oﬀ, and OUT voltage is 9V.

Ordering Information appears at end of data sheet.

5) Change JU3 to the 1–2 position. Connect the load

box to OUT.

6) Increase the load current and verify the OUT voltage

goes down when output current goes up to about 2A,

and D3 turns on (when overcurrent is in high current

mode, FLAG is asserted).
