PIN DESCRIPTIONS
Description
Power Supply Voltage Input to the internal PFET switch.
Analog Supply Input.
Enable Input. Set this digital input high for normal operation. For shutdown, set this pin low.
Voltage Control Analog input. VCON controls VOUT in PWM mode.
Feedback Analog Input. Connect to the output at the output filter capacitor.
Analog and Control Ground
Power Ground
Switch 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 LM3208.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
