Chip Information
PROCESS: BiCMOS
3) Connect the exposed pad of the IC to the SGND
plane. Do not make a direct connection between the
exposed pad plane and SGND (pin 2) under the IC.
Connect the exposed pad and pin 2 to the SGND
plane separately. Connect the ground connection of
the feedback resistive divider, the soft-start capaci-
tor, the adjustable reset timeout capacitor, and the
compensation network to the SGND plane. Connect
the SGND plane and PGND plane at one point near
the input bypass capacitor at V
IN .
4) Use the large SGND plane as a heatsink for the
MAX5096/MAX5097. Use large PGND and LX
planes as heatsinks for the rectifier diode and the
inductor.
