PIN DESCRIPTION
Output 2 Error Amplifier inverting input
Output 2 remote sense amplifier output.
Output 2 remote sense amplifier input. Connect to output at the load.
Output 2 remote sense amplifier input. Connect to ground at the load.
Output 1 remote sense amplifier input. Connect to ground at the load.
Output 1 remote sense amplifier input. Connect to output at the load.
Output 1 remote sense amplifier output.
Inverting input to the output 1 Error Amplifier
Output 1 error amplifier output
Programs the output 1 constant converter output current limit and hiccup over-
current threshold through an external resistor tied to VDAC1 and an internal
current source from this pin. Over-current protection can be disabled by
connecting a resistor from this pin to VDAC1 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).
Output 1 reference voltage programmed by the VID inputs and error amplifier
non-inverting input. Connect an external RC network to LGND to program
dynamic VID slew rate and provide compensation for the internal buffer
amplifier.
Programs output 1 startup and over current protection delay timing. Connect an
external capacitor to LGND to program.
Output 1 average current input from the output 1 phase IC(s). This pin is also
used to communicate over voltage condition to phase ICs.
Output 1 Buffered IIN signal. Connect an external RC network to FB1 to
program converter output impedance.
Connect a resistor to LGND to program oscillator frequency and OCSET,
VDAC1 and VREF2 bias currents. Oscillator frequency equals switching
frequency per phase. The pin voltage is 0.6V during normal operation and
higher than 1.6V if over-voltage condition is detected.
Open collector output. Asserted when Output 1 is regulated.
Local Ground for internal circuitry and IC substrate connection.
Clock output at 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.
Output of the voltage regulator, and power input for clock oscillator circuitry.
Connect a decoupling capacitor to LGND.
Non-inverting input of the voltage regulator error amplifier. Output voltage of the
regulator is programmed by the resistor divider connected to VCCL.
Output of the VCCL regulator error amplifier to control external transistor. The
pin senses the converter input voltage through a resistor.
Open collector output. Asserted when Output 2 output is regulated.
