Power Dissipation
The power dissipated in the MAX682/MAX683/MAX684
depends on output current and is accurately described
by:
P DISS = I OUT (2V IN - V OUT )
P DISS must be less than that allowed by the package
rating. See the Absolute Maximum Ratings for 8-pin
μMAX (MAX683/MAX684) and SO (MAX682) power-
dissipation limits and deratings.
Layout Considerations
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
Paralleling Devices
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 X ) and input
capacitor. For best performance, the paralleled devices
should operate in the same mode (skip or constant fre-
quency).
