The power dissipated in the MAX682/MAX683/MAX684
depends on output current and is accurately described
by:
P
rating. See the Absolute Maximum Ratings for 8-pin
µMAX (MAX683/MAX684) and SO (MAX682) power-
dissipation limits and deratings.
All capacitors should be soldered in close proximity to
the IC. Connect ground and power ground through a
short, low-impedance trace. If a high-value resistor is
driving the shutdown input and is picking up noise (i.e.,
frequency jitter at CXP and CXN), bypass SHDN to
GND with a small capacitor (0.01µF).

The MAX682/MAX683/MAX684 can be paralleled to
yield higher load currents. The circuit of Figure 6 can
deliver 500mA at 5V. It uses two MAX682s in parallel.
The devices can share the output capacitors, but each
one requires its own transfer capacitor (C
capacitor. For best performance, the paralleled devices
should operate in the same mode (skip or constant fre-
quency).
