Automatic Bypass Disable. Use this digital input to control Automatic Bypass mode. Set:
ABD = low to enable automatic bypass mode
ABD = high to disable automatic bypass mode
Bypass. Use this digital input to command operation in Forced Bypass mode. Set BYP = 0V
for normal operation.
Enable Input. Set this digital input high for normal operation. For shutdown, set low.
Power Ground
Switching Node connection to the internal PFET switch and NFET synchronous rectifier.
Power Supply Voltage Input to the internal PFET switch. Connect to the input filter capacitor
(
Figure 1
).
Feedback Analog Input. Connect to the output at the output filter capacitor (
Figure 1
).
