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

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.
