sDetermining the chopper frequency
Determining TOFF
The SLA7000M series are self-excited choppers. The chopping
OFF time TOFF is fixed by r3/C1 and r4/C2 connected to terminal
Td.
TOFF can be calculated using the following formula:
22
TOFF≅−r3 • C1rn (1−
=−r4 • C2rn (1− )
Vb Vb
The circuit constants and the TOFF value shown below are rec-
ommended.
TOFF = 12µs at r3=47kΩ, C1=500pF, Vb=5V
