PRODUCTION DATA
The MOSFET gate driver of the device is sourced from VCC. The maximum gate charge is limited by the 35-mA VCC sourcing current limit.
A leadless package is preferred for high switching-frequency designs. The MOSFET gate capacitance should be small enough so that the gate voltage is fully discharged during the off-time.
