It is required VIN 1 Power to place the input capacitor nearby the VIN pin and PGND. An external resistor from R to VIN pin sets the on-time and frequency of the ON RON 2 Input application. Connecting this pin to GND disables the device. Connecting this pin to a voltage higher than 1.18V typ. (but <6.5V) or leaving it floating enables the device. This pin EN 3 Input can be used in order to set an external UVLO through a resistor divider. If this pin is left floating the device is always on. The analog ground pin is the reference point for all stated voltages. It is internally AGND 4 Supply connected to PGND. For the soft-start function there is an internal 8A current source which charges an SS 5 Input external capacitor (CSS) to generate the soft-start. A minimum capacitance is required The feedback pin is internally connected to the regulation circuitry, the overvoltage and short-circuit comparators. The regulation reference point is 0.8V at this input pin. FB 6 Input Connect the feedback resistor divider between the output and AGND to set the output voltage. The output voltage pin is connected to the internal inductor. For the best stability and VOUT 7 Power operation connect the output capacitor between this pin and PGND. Exposed Pad Main node for switch current of the internal low-side MOSFET. Used PGND EP Power as heat sink for power dissipation during operation. we-online.com Wrth Elektronik eiSos GmbH & Co.
