Pcircuit = [(+VCC) – (-VCC)]2 / 1.77kΩ
Pxxx = [(±VCC) – Vout – (Icol) (Rcol + 6)]
(% duty cycle)
(Icol)
(For positive Vo and VCC, this is the power in the
npn output stage.)
(For negative Vo and VCC, this is the power in the
pnp output stage.)
Icol = Vout/Rload or 3mA, whichever is greater.
(Include feedback R in Rload.)
Rcol is a resistor (33Ω recommended) between the
xxx collector and ±VCC.
Tj (pnp) = Ppnp (200 + θca) + (Pcir + Pnpn)θca + Ta,
similar for Tj (npn).
Tj (cir) = Pcir (17.5 + θca) + (Ppnp + Pnpn)θca + Ta.
