General Description

The MAX5092 evaluation kit (EV kit) is a fully assembled

and tested surface-mount printed-circuit board (PCB)

demonstrating the MAX5092B, a low-dropout (LDO) reg-

ulator with internal boost preregulator. The EV kit oper-

ates from a 4V to 72V input voltage and delivers up to

250mA from a preprogrammed 7V boost preregulator

output (BSOUT) and 5V LDO output (VOUT). Both the

LDO and the boost preregulator output voltages are pro-

grammable using external resistors.

The MAX5092 EV kit features include on-board jumper

settings that allow for evaluation of the ENABLE and

HOLD functions of the MAX5092, a power-on-reset out-

put (

RESET) to indicate LDO out-of-regulation condi-

tions, and a programmable

RESET time period.

The MAX5092 EV kit can be configured to demonstrate

the MAX5092A (3.3V LDO output) or the MAX5093A/

MAX5093B. To evaluate the MAX5092A, replace the IC

with the MAX5092A. To evaluate the MAX5093_, the

addition of an external Schottky diode is required. See

the

Configuring for the MAX5093_ section to modify the

MAX5092 EV kit for the MAX5093_.

The EV kit comes fully assembled and tested, is quali-

fied lead-free, and is rated for an operating temperature

range of 0°C to +70°C.

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 con-

nected to it, must be careful to follow safety procedures

appropriate when working with high-voltage electrical

equipment.
