Attention: the heatsink of the IC must be isolated against ground of the application (it is connected to pin 4).
(1) With C_S2 (typical value between 47 and 150 nF) the flyback time and the noise behaviour can be optimized.
(2) With R5 capacitor C_F will be charged during scan and the value (typical value between 150 and 270 Ω) depends on I_defl, t_flb and C_F.
(3) R6 reduces the power dissipation of the IC. The maximum possible value depends on the application.
