Voltage ID DAC input. Pull to V
A resistance from this pin to ground programs the oscillator frequency according to f
trimmed output voltage of 2 V.
Overcurrent shutdown threshold setting. Connect this pin to the ROSC pin via a resistor divider as shown in
the Application Schematics. To disable the overcurrent feature, connect this pin directly to the ROSC pin. To
guarantee correct operation, this pin should only be connected to the voltage generated by the ROSC pin; do
not connect this pin to any externally generated voltages.

Bidirectional Gate Drive Enable
PWM output pulse to gate driver. 3-level output: Low = LSFET Enabled, Mid = Diode Emulation Enabled,
High = HSFET Enabled

Monitor a 12 V input through a resistor divider.
Power for the internal control circuits.
DAC Feed Forward Output
Power Saving Control. Low = power saving operation, High = normal operation. PSI signal has higher priority
over APSI_EN signal.
APSI_EN High: Enable AUTO PSI function. When PSI = low, system will be forced into PSI mode, uncondi‐
tionally. When PSI = high, APSI_EN will determine if the system needs to be in AUTO PSI mode. Once in
AUTO PSI mode, system switches on/off PSI functions automatically based on VID change status.
Open collector
PH_PSI Pin select one or two phase operation in PSI mode. PH_PSI = high, two phase operation, PH_PSI =
low, one phase operation.
