)
Bypass. Use this digital input to command operation in Bypass mode. Set BYP low for PWM
operation.
Enable Input. Set this digital input high after Vin
>
2.7V for normal operation. For shutdown, set
low.
Power Ground
Switching Node connection to the internal PFET switch and NFET synchronous rectifier.
Connect to an inductor with a saturation current rating that exceeds the maximum Switch Peak
Current Limit specification of the LM3203.
Power Supply Voltage Input to the internal PFET switch and Bypass FET. (
