SS6383(G)

PIN DESCRIPTIONS

PIN 1:

VIN

- Input supply pin - provides

power to create the external

reference voltage using a

resistor divider for regulating

PIN 2:

GND

- Ground pin.

PIN 3:

VREF - Reference voltage input. Pull this

pin low to shut the device down.

PIN 4:

VOUT - Output pin.

PIN 5~8: VCNTL - Input supply pin - supplies all

the internal control circuitry.

APPLICATION INFORMATION

Layout Consideration

The SS6383 is in an SO-8 package and is unable

to dissipate heat easily when operating with high

currents. In order to avoid exceeding the maximum

junction temperature, an appropriate area of copper

must be used.

be used to assist the heat dissipation. Vias to lead

heat into the bottom layer are also recommended.

All capacitors should be placed as close to the

relative IC pin as possible.
