TDA6101Q
TEST AND APPLICATION INFORMATION
Dissipation
Regarding dissipation, distinction must first be made
between static dissipation (independent of frequency) and
dynamic dissipation (proportional to frequency).
The static dissipation of the TDA6101Q is due to high and
low voltage supply currents and load currents in the
feedback network and CRT.
The static dissipation equals:
Rfb = value of feedback resistor.
Ioc = DC value of cathode current.

The dynamic dissipation equals:
Pdyn =VDDH × (CL +Cfb +Cint) × fi × Vo(p-p) ×δ
CL = load capacitance.
Cfb = feedback capacitance (≈ 150 fF).
Cint = internal load capacitance (≈ 4 pF).
fi = input frequency.
Vo(p-p) = output voltage (peak-to-peak value).
δ = non-blanking duty-cycle (≈ 0.8).
The IC must be mounted on the picture tube base print to
minimize the load capacitance (CL).
