TECHNICAL D A T A
KIA6220H
BIPOLAR LINEAR INTEGRATED CIRCUIT
30W BTL DUAL AUDIO POWER AMPLIFIER.
The thermal resistance 6 j-c of KIA6220H package
CPP-17(Compact Power Package 17pin), designed
for low thermal resistance, has high efficiency of
heat radiation.
The temperature rise of chip can be reduced, and the
influence from the degradation of the features due to
the temperature rise at the high output can also be
reduced.
This stereo audio power IC, designed for car audio
use, has two built-in channels to reduce the
characteristic difference between L and R channels.
It also contains output short detection circuit,
output clip detection and various kind of protection.

For example, when Rf=0Q, Gv is obtained
by the expression (1) and (2) as shown below.
Gv^24+20+6=50 (dB)
The voltage gain is reduced when Rf is
increased. (Fig. 2)
With the voltage gain reduced, since (1) the
oscillation stability is reduced, and (2) the
pop noise changes when Vcc is set to ON,
refer to the items 3 and 4.

2. Stand-by SW Function
By means of controlling ® pin (Stand-by terminal) to High and Low, the power
supply can be set to ON and OFF.
The threshold voltage of ® pin is set at about 3V(Typ.), and the power supply
current is about lM(Typ.) at the stand-by state.
(Fig.3) With © Pin set to High, Power is t u r n e d ON.
