(10) Chopping frequency setting
For constant-current control, this IC performs chopping operations at the frequency determined by the capacitor
(Cchop) connected between the CHOP pin and GND.
The chopping frequency is set as shown below by the capacitor (Cchop) connected between the CHOP pin and GND.
Tchop ≒ C × V × 2 / I (s)
V : Width of suresshu voltage, typ 0.5V
I : Charge/discharge current, typ 10
μA
For instance, when Cchop is 200pF, the chopping frequency will be as follows :
Fchop ≒ 1 / Tchop (Hz)
