Operating Temperature

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

Rise Time

In electronics, when describing a voltage or current step function, rise time is the time taken by a signal to change from a specified low value to a specified high value.

70ns

Synchronous Rectifier

Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).

Yes

Fall Time (Typ)

35 ns

Nominal Input Voltage

The actual voltage at which a circuit operates can vary from the nominal voltage within a range that permits satisfactory operation of equipment. The word “nominal” means “named”.

Clock Sync

Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates.
