? Fast ON/OFF (cycle-by-cycle)
? Active-on or active-off control
? Low consumption in remote off
state
? Active-on control for fail-safe
? Eliminates expensive in-line
on/off switch
? Allows processor controlled turn
on/off
? Permits shutdown/wake-up of
peripherals via LAN or parallel
port
? Synchronization to external lower
frequency signal
? Starts new switching cycle on
demand
? Automatic recovery from thermal
fault
? Large hysteresis prevents circuit
board overheating
? 10% Higher power capability due
to tighter tolerance
