MAX8815A Evaluation Kit
Evluates:MX815A
General Description
Features
o Up to 97% Efficiency with Internal Synchronous
The MAX8815A evaluation kit (EV kit) is a fully assem-
bled and tested printed-circuit board (PCB) for evaluat-
ing the MAX8815A step-up converter. The MAX8815A
is a 1A (maximum load), 97% efficient, 35µA quiescent
current step-up converter with True Shutdown™ and is
ideal for use in DSC, DVC, and other handheld appli-
cations. The MAX8815A EV kit is designed for a 5V
output and also provides a jumper for evaluation of
fixed-frequency pulse-width-modulation mode (FPWM)
or normal mode.
Rectifier
o Low 35µA (Switching) Quiescent Current
o Guaranteed 1A Output Current at 5V from 2.5V Input
o Guaranteed 500mA Output Current at 5V from 1.8V
Input
