Series
MAX17019r
Datasheet
19-4941; Rev 0; 9/09
The MAX17019 evaluation kit (EV kit) presents the
MAX17019 high input-voltage quad-output controller in a
typical application setup. The EV kit operates from a 5.5V
to 38V input range. The high input voltage of 38V makes
this device ideal for automotive applications.
High-voltage controller A is used to generate a 5V rail
that serves as supply for the other three rails. These rails
are generated by two switching converters (rails B and
C), and one push-pull linear regulator (rail D). The sup-
plies for converters B and C and regulator D are acces-
sible but must be less than 6V.
The MAX17019 also has an internal fixed 5V linear regu-
lator capable of supplying 50mA. The EV kit operates at
0.5MHz (VOUTA and VOUTC) and at 1MHz switching
frequency (VOUTB). The EV kit has superior line- and
load-transient response.
