PIN DESCRIPTION
Inputs to VID D to A Converter.
Remote Sense Input. Connect to ground at the Load.
Connect a resistor to VOSNS- to program oscillator frequency and OCSET, FB, and
VDAC bias currents.
Regulated voltage programmed by the VID inputs. Connect an external RC network
to VOSNS- to program Dynamic VID slew rate and provide compensation for the
internal Buffer Amplifier.
Programs the hiccup over-current threshold through an external resistor tied to
VDAC and an internal current source. Over-current protection can be disabled by
connecting a resistor from this pin to VDAC to program the threshold higher than the
possible signal into the IIN pin from the Phase ICs but no greater than 5V (do not
float this pin as improper operation will occur).
Current Sense input from the Phase IC(s). If current feedback from the Phase ICs is
not required for implementing droop or over-current protection connect to the LGND
pin. To ensure proper operation do not float this pin.
Buffered IIN signal. Connect an external RC network to FB to program converter
output impedance.
Inverting input to the Error Amplifier. Converter output voltage is offset from the
VDAC voltage through an external resistor connected to the converter output voltage
at the load and an internal current source.
Output of the Error Amplifier.
6.8V/5mA Regulated output used as a system reference voltage for internal circuitry
and the Phase ICs.
Power Input for internal circuitry.
Local Ground for internal circuitry and IC substrate connection.
Oscillator Output voltage. Used by Phase ICs to program Phase Delay
Controls Converter Start-up and Over-Current Timing. Connect an external capacitor
to LGND to program.
Open Collector output that drives low during Start-Up and any external fault
condition. Connect external pull-up.
Enable Input. A logic low applied to this pin puts the IC into Fault mode. Do not float
this pin as the logic state will be undefined.
