TERMINAL FUNCTIONS
TERMINAL
DESCRIPTION
NAME
NO.
The Enable input is an open-base logic input that is referenced to VI–. Two ON/OFF enable options are available,
positve logic and negative logic. Positive logic devices are enabled by applying a logic high voltage (Open) and
are disabled by applying a logic low voltage (VI–). Negative logic devices are enabled by applying a logic low
voltage (VI–) and are disabled by applying a logic high voltage (Open). See the Application Information section for
Enable/Sync (1)

more detailed information.
This pin also has the option of a synchronization input. A module that has the synchronization option does not
have ON/OFF enable control. A 5-V logic signal greater than the free-running frequency but
≤ 350 kHz is required
for synchronization control. See the Application Information section for more detailed information.
The negative input supply for the module, and the 0-V reference for the Enable/Sync inputs. When powering the

module from a positive source, this input is connected to the input source return.
The positive input for the module with respect to VI–. When powering the module from a negative input voltage,

this input is connected to the input source ground.
VO+

This is the positive power output with respect to VO–. It is dc isolated from the input power pins.
This pin allows the output voltage set point of the module to be increased or decreased up to
± 10 %. Connecting
a resistor between this terminal and VO+ decreases the output voltage set point. Connecting a resistor between
this terminal and VO– increases the output voltage set point. A 0.05-W rated resistor may be used, with tolerance

and temperature stability of 1% and 100 ppm/
°C, respectively. If left open circuit, the converter output voltage
defaults to its nominal value. The specification table gives the standard resistor values for the most common
output voltages.
This is the output power return for the VO+ bus. This terminal should be connected to the common of the load
