MAX1846 Evaluation Kit
General Description
The MAX1846 evaluation kit (EV kit) contains both the
MAX1846 and MAX1847. Both devices are inverting,
current-mode, constant-frequency PWM controllers.
The MAX1846 circuit is configured for a +12V input and
a -5V output at 2A. The MAX1847 circuit is configured
for a +3.3V input and a -12V output at 400mA. Each cir-
cuit is powered separately so there is no interaction
between the two circuits. The MAX1846 is available in a
10-pin 碌MAX package and the MAX1847 is available in
a 16-pin QSOP package.
The MAX1846 EV kit is a fully assembled and tested
surface-mount circuit board. With minimal modification,
it can also be used to evaluate other output voltages.
