MAX17083 Evaluation Kit
Evluates:MAX17083
General Description
Features
o 2.4V to 5.5V Input Range
The MAX17083 evaluation kit (EV kit) is a fully assem-
bled and tested PCB that demonstrates the typical 5A
application circuit of the MAX17083. The MAX17083 is a
DC-DC converter that steps down the system’s 3.3V or
5V input supply for low-voltage, low-power applications.
o Configured for 1.1V Output Voltage
o Adjustable Output-Voltage Range (0.75V to 2.7V)
o 5A Output Current
The MAX17083 EV kit provides a 1.1V output voltage from
a 2.4V to 5.5V input range. It delivers up to 5A output cur-
rent while achieving greater than 90% efficiency.
Programmed through jumper JU4, the EV kit operates at
1MHz switching frequency and has superior line- and
load-transient response. The EV kit also allows the evalua-
tion of other adjustable output voltages from 0.75V to
2.7V, by varying the SET pin and changing resistors R3
and R4.
o 90% Efficiency (V = 3.3V, V
= 1.1V at 2A)
