MAX5097A Evaluation Kit

Evluates:MX5097A

General Description

Features

The MAX5097A evaluation kit (EV kit) demonstrates the

MAX5097A in a standard application circuit demon-

strating high efficiency. The EV kit circuit features a

MAX5097A IC in a 16-pin TQFN package. The EV kit

can operate from a 5V to 40V input source.

♦ 5V to 40V Input Voltage (Buck Mode)

♦ 4V to 40V Input Voltage (LDO Mode)

♦ 3.3V Output at Up to 600mA (Buck Mode)

♦ Low Quiescent Current 3.3V Output at Up to

The MAX5097A EV kit includes a current-mode DC-DC

step-down regulator (Buck Mode) and a selectable low-

quiescent-current LDO regulator for operation at light-

load (LDO Mode). The step-down regulator provides a

3.3V output with up to 600mA output current. In LDO

Mode, the MAX5097A IC provides up to 100mA output

current. The EV kit circuit’s step-down regulator oper-

ates at a switching frequency of 330kHz, thus allowing

the use of small ceramic capacitors at the output. The

MAX5097A is capable of synchronizing to an external

digital clock.

100mA (LDO Mode)

♦ Configurable Output Voltage

♦ 330kHz Switching Frequency

♦ Capable of Synchronizing to an External Clock

♦ Open-Drain RESET Output PCB Pad

♦ Surface-Mount Components

♦ Fully Assembled and Tested

Ordering Information

The MAX5097A EV kit can be reconfigured for other

output voltages by selecting appropriate external com-

ponents. The EV kit circuit features soft-start, output

current-limit, and an open-drain active-low reset output

PCB pad.
