Evaluates: MAXM17543 in 3.3V

Output-Voltage Application

MAXM17543 3.3V Output

Evaluation Kit

General Description

The MAXM17543 evaluation kit (EV kit) is a demonstration

circuit of MAXM17543 high-voltage, high-efficiency,

current-mode scheme, synchronous step-down DC-DC

switching power module. The EV kit is designed for a 3.3V

output and delivers up to 2.5A load current from a wide

input-voltage range of 4.5V to 42V. The EV kit switches at

an optimal 500kHz switching frequency to allow the use of

small component-sizes, helping to minimize solution-size

while maintaining high-performance. The EV kit provides

a precision-enable input, an open-drain RESET output

signal, and external frequency synchronization to provide

a simple and reliable startup sequence and eliminate beat

frequency between regulators. The EV kit also includes

optional component footprints to program different output

voltages, an adjustable input undervoltage-lockout, and a

soft-start time to control inrush current during startup. The

MAXM17543 IC data sheet provides a complete description

of the part and should be read in conjunction with this data

sheet prior to modifying the demonstration circuit.
