Philips Semiconductors Product specification
Vertical deflection power amplifier for
monitors
TDA4860
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134); voltages referenced to substrate (pin 6); unless
otherwise specified.
Notes
1. Internally limited by thermal protection; switching temperature point at 160
±
8
°
C.
2. Equivalent to discharging a 200 pF capacitor through a 0
Ω
series resistor.
THERMAL CHARACTERISTICS
The heatsink can be estimated according to application circuit (see Fig.1):
.
A heatsink is needed at R

< 10 K/W and R
th c-h
= 0.5 K/W (using silicon grease) with
R
th h-a
= 22.2 K/W
−
(10 + 0.5) K/W = 11.7 K/W.
