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.

DAC Feed Forward Output
Power Saving Control. Low = single phase operation, High = normal operation.
Threshold sensitive input for thermal monitoring
Open collector
Open collector output indicates the state of the thermal monitoring input. Low impedance output indicating a
normal status when the voltage of NTC pin is above the specified threshold. This pin will transition to high
impedance when the voltage of NTC pin decrease (temperature increase) below the specified threshold.
This pin requires an external pullup resistor
