Layout Guidelines
Good thermal contact between the MAX5902/
MAX5903 and the external MOSFET is essential for the
thermal shutdown feature to operate effectively. Place
the MAX5902/MAX5903 as close as possible to the
drain of the external MOSFET, and use wide circuit
board traces for good heat transfer. See Figure 7 for an
example of a PC board layout.
