Quick Start

Recommended Equipment

Before beginning, the following equipment is needed:

•

One variable-DC power supply (further referred to

as PS1) capable of supplying up to 72V at 1A

•

One adjustable load capable of sinking 250mA at 5V

•

Three digital voltmeters (DVMs)

•

One ammeter (for optional low-quiescent input cur-

rent evaluation)

Procedure

The MAX5092 EV kit is fully assembled and tested.

Follow the steps below to verify board operation. See

Figure 1 for test setup.

Warning: The MAX5092 EV kit is designed to operate

with high voltages. Dangerous voltages can be present

on this EV kit and on equipment connected to it. Users

who power up this EV kit, or the power sources connected

to it, must be careful to follow safety procedures appropri-

ate when working with high-voltage electrical equipment.

1) Preset PS1 to +4V. Turn off PS1. Caution: Do not

turn on the power supply until all connections are

complete.

2) Connect the positive terminal of PS1 to the VIN pad

located on the EV kit. Connect the negative terminal

of PS1 to the GND pad located on the EV kit.

3) Connect the positive input of one DVM to the VIN

pad located on the EV kit. Connect the negative

input of that DVM to the GND pad located on the EV

kit. This DVM measures the EV kit input voltage.

4) Connect the positive input of the second DVM to

the BSOUT pad located on the EV kit. Connect the

negative input of that DVM to the GND pad located

on the EV kit. This DVM measures the output volt-

age at the boost converter output.

5) Connect the positive input of the third DVM to the

VOUT pad located on the EV kit. Connect the nega-

tive input of that DVM to the GND pad located on

the EV kit. This DVM measures the output voltage at

the LDO output.
