Pin Functions

EN/UVLO: Shutdown and Undervoltage Detect Pin. The

LT8330 is shut down when this pin is low and active

when this pin is high. Below an accurate 1.6V threshold

the part enters undervoltage lockout and stops switching.

This allows an undervoltage lockout (UVLO) threshold to

be programmed for system input voltage by resistively

dividing down system input voltage to the EN/UVLO pin.

An 80mV pin hysteresis ensures part switching resumes

when the pin exceeds 1.68V. EN/UVLO pin voltage below

0.2V reduces VIN current below 1µA. If shutdown and

UVLO features are not required, the pin can be tied directly

to system input.

FBX: Voltage Regulation Feedback Pin for Positive or

Negative Outputs. Connect this pin to a resistor divider

between the output and GND. FBX reduces the switching

frequency during start-up and fault conditions when FBX

is close to GND.

GND: Ground Connection for the LT8330. The DFN pack-

age has the best thermal performance due to an exposed

pad (Pin 9) on the bottom of the package. This exposed

pad must be soldered to a ground plane. Pin 5 of the DFN

package (and Pin 2 of the TSOT package) should also be

connected to a ground plane. The ground plane should be

connected to large copper layers to spread heat dissipated

by the LT8330.

INTVCC: Regulated 3V Supply for Internal Loads. The

INTVCC pin must be bypassed with a minimum 1µF low ESR

ceramic capacitor to ground. No additional components

or loading is allowed on this pin.

NC: No Internal Connection. Tie directly to local ground.

SW: The Output of Internal Power Switch. Minimize the

metal trace area connected to this pin to reduce EMI.

VIN: Input Supply. This pin must be locally bypassed. Be

sure to place the positive terminal of the input capacitor as

close as possible to the VIN pin, and the negative terminal

as close as possible to the GND pin.
