MAX1896 Evaluation Kit
General Description
The MAX1896 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that contains a
fixed-frequency 1.4MHz, pulse-width-modulated
(PWM), step-up DC-DC converter. The EV kit provides
a 12.0V output voltage from a 2.5V to 5.5V input source.
It delivers up to 100mA output current.
The EV kit provides low quiescent current and high effi-
ciency. It can also be used to evaluate other output
voltages from VIN voltage up to 13.0V by changing the
feedback resistors, R1 and R2.
