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 APW 7065C PW M 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.
