The CS pin is checked at start−up (cold start−up or after

to the pin and no DRV pulse is generated until the CS pin

impedance to be placed on the CS pin for operation is then

120

W. In practice, it is recommended to place more than

250

W to take into account possible parametric deviations.

Also, along the circuit operation, the CS pin could happen

to be grounded. If it is grounded, the MOSFET

conduction time is limited by the 20

ms maximum

on−time. If such an event occurs, a new pin impedance

test is made.
