Description
Signal Power Supply Voltage (Input): This pin is connected externally to the PVIN pin. A 22µF
ceramic capacitor from the SVIN pin to SGND must be placed next to the IC.
Power Ground: Internal ground connection to the source of the internal N-Channel MOSFETs.
Switch (Output): This is the connection to the drain of the internal P-Channel MOSFET and drain
of the N-Channel MOSFET. This is a high-frequency, high-power connection; therefore traces
should be kept as short and as wide as practical.
Exposed Pad (Power): Must be connected to a GND plane for full output power to be realized.
