Output Power Pins +OUT And -OUT:

The output power terminals OUT(+) and OUT(-)

deliver the 18A maximum output current from the

PI3101

through

the

J-lead

output

pins.

This

configuration allows for a low impedance output and

should be connected to multi-layer PCB parallel

planes for best performance. Due to the high

switching frequency, output ripple and noise can be

easily attenuated by adding just a few high quality

X7R ceramic capacitors while retaining adequate

transient

response

for

most

applications.

The

PI3101

does

not

require

any

feedback

loop

compensation nor does it require any opto-isolation.

All isolation is contained within the package. This

greatly simplifies the use of the converter and

eliminates all outside influences of noise on the

quality of the output voltage regulation and feedback

loop. It is important for the user to minimize resistive

connections from the load to the converter output

and to keep stray inductance to a minimum for best

regulation and transient response. The very small

size footprint and height of the PI3101 allows the

converter to be placed in the optimum location to

allow for tight connections to the point of load. For

those applications absolutely requiring very tight

regulation,
