MAX15049 Evaluation Kit

General Description

The MAX15049 evaluation kit (EV kit) is a fully assembled

and tested PCB that demonstrates the capabilities of

the MAX15049. The MAX15049 is a high-performance,

triple-output synchronous buck controller with sequenc-

ing capability. The EV kit requires a 5V to 16V (12V, typ)

DC input-voltage range for normal operation.

The MAX15049 EV kit outputs are configured for 3.3V,

1.8V, and 1.2V. They provide a load current of 3A, 3A,

and 6A, respectively. The EV kit’s switching frequency

is set to 500kHz, but can be programmed up to 1.2MHz

by replacing a resistor. The EV kit comes configured

for sequencing (MAX15049) and is capable of prebias

startup. The EV kit can also be used to evaluate the

MAX15048 for tracking applications by changing a few

components. The PGOOD logic signal output pad is

provided for circuit monitoring.

The MAX15049 EV kit comes with a MAX15049ETJ+

installed. To evaluate the MAX15048, contact the factory

for samples of the pin-compatible MAX15048ETJ+.
