MAX1536 Evaluation Kit
General Description
The MAX1536 evaluation kit (EV kit) provides dynami-
cally adjustable 1.5V/1.8V output voltages from a 3.0V
to 5.5V input voltage source. It delivers up to 3.6A out-
put current with up to 93% efficiency.
The MAX1536 EV kit includes the MAX1536 step-down
switching regulator with an internal synchronous rectifi-
er to increase efficiency and reduce the number of
external components. The resistor-programmable fixed-
off-time, current-mode architecture allows an optimum
response to load-and-line transients. This EV kit, as
configured, operates at approximately 570kHz and is
optimized for 3.3V input and 1.8V output.
The EV kit is a fully assembled and tested circuit board.
It also allows the evaluation of other output voltages in
the 0.7V to VIN range.
