PIN DESCRIPTION
Inputs to VID D to A Converter.
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.
Open collector output of the VRHOT comparator which drives low if HOTSET pin
voltage is lower than 1.6V. Connect external pull-up.
A resistor divider including thermistor senses the temperature, which is used for
VRHOT comparator.
Remote sense amplifier input. Connect to ground at the load.
Remote sense amplifier input. Connect to output at the load.
Remote sense amplifier output. Used for OV detection
Inverting input to the Error Amplifier.
Output of the error amplifier.
Buffered, scaled and thermally compensated IIN signal. Connect an external RC
network to FB to program converter output impedance.
Node for DCR thermal compensation network.
Buffered VDAC.
Error amplifier non-inverting input. Converter output voltage can be decreased from
the VDAC voltage with an external resistor connected between VDAC and this pin
(there is an internal sink current at this pin).
Regulated voltage programmed by the VID inputs. Connect an external RC network
to LGND to program dynamic VID slew rate and provide compensation for the
internal buffer amplifier.
Programs converter startup and over current protection delay timing. It is also used
to compensate the constant output current loop during soft start. Connect an
external capacitor to LGND to program.
Connect a resistor to LGND to program oscillator frequency and VSETPT bias
current. Oscillator frequency equals switching frequency per phase. The pin voltage
is 0.6V during normal operation and higher than 1.6V if an over-voltage condition is
detected.
Local Ground for internal circuitry and IC substrate connection.
Clock frequency is the switching frequency multiplied by phase number. Connect to
CLKIN pins of phase ICs.
Phase clock output at switching frequency per phase. Connect to PHSIN pin of the
first phase IC.
Feedback input of phase clock. Connect to PHSOUT pin of the last phase IC.
Voltage regulator and IC power input. Connect a decoupling capacitor to LGND.
Average current input from the phase IC(s). This pin is also used to communicate
over voltage condition to phase ICs.
Output of the VCCL regulator error amplifier to control external transistor. The pin
senses 12V power supply through a resistor.
Open collector output that drives low during startup and under any external fault
condition. Connect external pull-up.
Voltage at this pin is proportional to load current.
