7 / 24 page 1997 Aug 14 7 Philips Semiconductors Preliminary specification 2 × 23 W high efficiency car radio power amplifier TDA1561Q Heatsink design There are two parameters that determine the size of the heatsink. The first is the rating for the virtual junction temperature and the second is the ambient temperature at which the amplifier must still deliver its full power in the BTL mode. With a conventional BTL amplifier, the maximum power dissipation with a music-like signal (at each amplifier) will be approximately two times 5 W. At a virtual junction temperature of 150 °C and a maximum ambient temperature of 60 °C, R th(vj-c) = 1.3 K/W and Rth(c-h) = 0.2 K/W, the thermal resistance of the heatsink should be: Compared to a conventional BTL amplifier, the TDA1561Q has a higher efficiency. The thermal resistance of the heatsink should be: 150 60 – 25 × ---------------------- 1.3 – 0.2 – 7.5 K/W = 1.7 150 60 – 25 × ---------------------- 1.3 – 0.2 – 13.8 K/W = Fig.3 Thermal equivalent resistance network. handbook, halfpage 3.6 K/W 0.6 K/W 3.6 K/W virtual junction OUT 1 OUT 1 case 3.6 K/W 0.6 K/W 3.6 K/W OUT 2 OUT 2 MGC424 0.1 K/W |
