4.3.2 Dynamic Mode:
Built-in Pulse Generator
: (Fig 4-4)
Major application :
Power supply load transient response testing, power recovery time testing, pulse load
simulation, power component testing
Description:
The maximum Rise/Fall current slew rate or minimum Rise/fall time is the time required for
the load input to change from 10% to 90% or from 90% to 10% of the programmed High to
Low load level.
• Rise slew rate = | Ilow - Ihigh | / Ta (A/us)
• Fall slew rate = (Ihigh - Ilow) / Tb (A/us)
• Rise time = Ta = | Ilow - Ihigh | / Rise slew rate
• Fall time = Tb = (Ihigh - Ilow) / Fall slew rate
Major application:
Simulate real load condition, Battery discharge testing
