Philips TDA4860

1997 Oct 27 5

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 Rth j-c < 10 K/W and Rth c-h = 0.5 K/W (using silicon grease) with

Rth h-a = 22.2 K/W −(10 + 0.5) K/W = 11.7 K/W.
