PIN DESCRIPTION
Feedback to the VCCVID regulator. Connect to the VCCVID output.
1.2V/150mA Regulator Output. Can also drive external pass transistor to minimize
on-chip power dissipation
Power for VID Pull-up resistors and VCCVID Regulator
Inputs to VID D to A Converter. On-chip 700 ohm pull-up resistors to VIDPWR pin
are included.
Used for precision post-package trimming of the VDAC voltage. Do not make any
connection to these pins.
Remote Sense Input. Connect to ground at the Load.
Connect a resistor to VOSNS- to program oscillator frequency and FB, OCSET,
BBFB, and VDAC bias currents
Regulated voltage programmed by the VID inputs. Current Sensing and PWM
operation are referenced to this pin. Connect an external RC network to VOSNS- to
program Dynamic VID slew rate.
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 this pin to a DC voltage no greater than 6.5V (do not float this pin as
improper operation will occur).
Current Sense input from the Phase IC(s). To ensure proper operation bias to at
least 250mV (don’t 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
Input to the Regulation Detect Comparator. Connect to converter output voltage and
VDRP pin through resistor network to program recovery from VID step-down.
Connect to ground to diable Body Braking
6.8V/5mA Regulated output used as a system reference voltage for internal circuitry
and the Phase ICs
Power for internal circuitry
Local Ground and IC substrate connection
Oscillator Output voltage. Used by Phase ICs to program Phase Delay
Inverting input to VRHOT comparator. Connect resistor divider from VBIAS to LGND
to program VRHOT threshold. Diode or thermistor may be substituted for lower
resistor for enhanced/remote temperature sensing. Applying a voltage exceeding
approximately 7.5V disables the oscillator for factory testing.
Open Collector output of the VRHOT comparator. Connect external pull-up.
Controls Converter Softstart, Power Good, and Over-Current Delay Timing. Connect
an external capacitor to LGND to program the timing. An optional resistor can be
added in series with the capacitor to reduce the over-current delay time.
Open Collector output that drives low during Softstart and any external fault
condition. Connect external pull-up.
Open Collector output of the VCCVID Power Good circuitry. Connect external pull-
up.
Connect an external capacitor to LGND to program the VCCVID Power Good delay
