It is required VIN 1 Power to place the input capacitor nearby the VIN pin and PGND. The Sync input pin allows for synchronization of the PWM operating frequency with an external frequency source. Apply a CMOS logic level square wave with a frequency SYNC 2 Input between 650 kHz and 950 kHz. When not using synchronization connect to ground. The module free running PWM frequency is 812kHz (typical). 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 and must be AGND 4 Supply connected to PGND. The feedback pin is internally connected to the regulation circuitry, the over-voltage and short-circuit comparators. The regulation reference point is 0.796V at this input FB 5 Input pin. Connect the feedback resistor divider between the output and AGND with the midpoint at this pin to set the output voltage. The Soft-Start and Tracking pin is to extend the 1.6ms internal soft-start by connecting SS/TRK 6 Input an external soft-start capacitor. To enable voltage tracking connect to an external resistive divider connected to a higher priority supply rail. 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 internal low-side MOSFET. Used as PGND EP Power heat sink for power dissipation during operation. Must be electrically connected to pin 4. we-online.com Wrth Elektronik eiSos GmbH & Co.
