MAX1711 Voltage Positioning Evaluation Kit
General Description
The MAX1711 evaluation kit (EV kit) demonstrates the
high-power, dynamically adjustable notebook CPU appli-
cation circuit with voltage positioning. Voltage positioning
decreases CPU power consumption and reduces output
capacitance requirements. This DC-DC converter steps
down high-voltage batteries and/or AC adapters, gener-
ating a precision, low-voltage CPU core V
CC
rail.
The MAX1711 EV kit provides a digitally adjustable
0.925V to 2V output voltage from a 7V to 24V battery input
range. It delivers sustained output current of 12A and
14.1A peaks, operating at a 550kHz switching frequency,
and has superior line- and load-transient response. The
MAX1711 EV kit is designed to accomplish output voltage
transitions in a controlled amount of time with limited input
surge current.
This EV kit is a fully assembled and tested circuit board.
