Function
Parallel sharing control bus for master-slave configuration.
Modulator control node input. Driven by external error amplifier in remote sense
operation.
VTM TM input for temperature compensation. Leave disconnected for remote
sense operation.
Enables power supply when allowed to float high. 5.0V during normal operation.
9.0V auxiliary bias voltage.
Selects operating mode. Adjusts output voltage in adaptive loop operation.
Current sense input for current limit and overcurrent protection in remote sense
operation. Leave disconnected for adaptive loop operation.
Do not connect this pin.
Signal ground, reference for analog controls. Kelvin connected internally to –IN
and -OUT.
Do not connect this pin.
Reference voltage for internal error amplifier in adaptive loop operation.
Powers and enables external control circuit voltage reference in remote sense
operation.
Adaptive loop gain control. Sets the magnitude of the adaptive loop load line in
adaptive loop operation. Leave disconnected for remote sense operation.
Bias voltage to power VTM module during startup
Positive input power terminal
Positive output power terminal
Negative input power terminal. Connected internally to –OUT.
Negative output power terminal. Connected internally to -IN.
