SYNCHRONIZATION
FIGURE 21-EXTERNAL DUTY CYCLE CLAMP AND
MULTI UNIT SYNCHRONIZATION
The diode clamp is required if the Sync amplitude is large enough to
the cause the bottom side of CT to go more than 300mV below
ground.

FIGURE 25-CURRENT SENSING POWER MOSFET
Virtually lossless current sensing can be achieved with the
implementation of a SENSEFET power switch.For proper operation
during over current conditions.a reduction of the Ipk(max) clamp
level must be implemented.Refer to Figure 22 and 24
