ware by the system through the on-chip DAC, but can
also be accomplished in hardware using an external
thermistor or IC temperature sensor. Figure 8 shows
how an NTC thermistor can be connected to make the
bias voltage increase with temperature.
PC Board Layout and Grounding
Careful PC board layout is important for minimizing
ground bounce and noise. In addition, keep all connec-
tions to FB as a short as possible. In particular, locate
feedback resistors (R5, R6, and R8) as close to FB as
possible. Use wide, short traces to interconnect large
current paths for N1, D1, L1, C1, C2. Do not share
these connections with other signal paths. Refer to the
MAX1932 EV kit for a PC board layout example.
