BLOCK DIAGRAM
Fig.1
Block diagram and application circuit with flyback supply voltage VP3 from an external source.
Deflection frequency range from 50 Hz to 100 Hz.
Assumed values:
Iyoke = 1.42 A.
Ryoke = 4.17 Ω +7%+ ∆R(T) = 6.12 Ω.
Lyoke = 5.25 mH.
R1 = 1.0 Ω±1%.
Tamb =65 °C.
Tj(max) = 105 °C.
Tyoke =75 °C.
Pyoke = 1.2 W.
PIC = 1.8 W.
Ptot = 3.0 W.
tp FLB = typically 250 µs.
Attention: the heatsink of the IC must be isolated against ground; the cooling fin is connected to pin 6.
