The MAX8552 MOSFET driver sources and sinks large
currents to drive MOSFETs at high switching speeds.
The high di/dt can cause unacceptable ringing if the
trace lengths and impedances are not well controlled.
The following PC board layout guidelines are recom-
mended when designing with the MAX8552:
1) Place all decoupling capacitors as close to their
2) Minimize the length of the high-current loop from
3) Provide enough copper area at and around the
respective IC pins as possible.

and the low-side MOSFET back to the input-capaci-
tor negative terminal.
switching MOSFETs and inductors to aid in thermal
dissipation.
