MAX15049 Evaluation Kit
General Description
Features
S Triple-Output Power Supply
VOUT1 (3.3V, 3A)
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.
VOUT2 (1.8V, 3A)
VOUT3 (1.2V, 6A)
S 5.5V to 16V Input-Voltage Operation (Design
Optimized for 12V Input)
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.
S Optional 4.5V to 5.5V Input-Voltage Operation
S 500kHz Switching Frequency per Converter
S Programmable Switching Frequency Up to 1.2MHz
S Sequencing Operation (Tracking Possible with
Component Changes)
S PGOOD Power Monitoring
S Small 1.5in x 1in Circuit Footprint
S 92.8% Peak Efficiency for OUT1
S Fully Assembled and Tested
The MAX15049 EV kit comes with a MAX15049ETJ+
installed. To evaluate the MAX15048, contact the factory
for samples of the pin-compatible MAX15048ETJ+.
