5.6 Rise and Fall Times
The CPC1560 has rise and fall times that are primarily
limited by internal parasitic elements of the device; the
load components only play a secondary role. This can
be appreciated in the turn-off graph of an application
circuit operating at 45V, where the slope of the load
voltage starts scooping down into a more capacitive
shape after approximately 15 volts.
5.7 Over-Voltage Protection
5.7.1 Stored Energy in the Load
During the CPC1560’s switching periods, energy is
transferred between the load components, the
CPC1560 device, and, if used, the over-voltage
protection circuitry.
When the output switch turns off, inductive loads
(LLOAD) transfer their stored energy into the MOSFET
switches, the load capacitance, and the over-voltage
protector. (See the turn-off graph for a 45V inductive
load application circuit.)
When the output switch turns on, the energy in the
load inductor is zero, and the load capacitor (CLOAD)
must transfer its stored energy into the MOSFET.
