APW7065C
Function Description (Cont.)
Shutdown and Enable
Pulling the COMP voltage to GND by an open drain
transistor, as shown in Typical Application Circuit,
shutdowns the APW7065C PWM controller. In shut-
down mode, the UGATE and LGATE turn off and pull to
PHASE and GND respectively.
Under Voltage Protection
The FB pin is monitored during converter operation by
the internal Under Voltage (UV) comparator. If the FB volt-
age drops below 50% of the reference voltage (50% of
0.8V = 0.4V), a fault signal is internally generated, and the
device turns off both high-side and low-side MOSFET
and the converter’s output is latched to be floating.
