Thermal Design Thermal design requires that conditions (max) 150°C 100°C met. Concerning (max), chip temperature each transistor given equation (1). (Tri) (Tri) (Tri) (°C) .(1) (Tri): thermal resistance each transistor chip itself (Tri): collector loss each transistor Increase case temperature Ambient temperature (Tri) each chip will (Tr1) (Tr4) 35°C/W .(2) loss transistors video pack varies with frequency. loss increases with frequency. example, maximum frequency will (clock), then transistors with largest losses will transistors emitter-follower (EF) stage. From (clock) figure, that that loss will total single channel. That stage) (1ch) 0.25 [W].(3) thermal design must assure that does exceed 150°C this time. Concerning Tc(max), relationship between (total) .(4) Taking increase into account, condition thermal design must meet becomes 100°C. Next design thermal conditions VP453 that meet conditions sections above.

VP453 Sample Thermal Design VP453 Conditions: class monitor, (clock). VOUT Vp-p Here consider case where such monitor operated ambient temperatures 60°C maximum frequency (clock). mentioned previously, chips with maximum loss will transistors emitter-follower stage. Equation follows from deriving that value from figure below equation (3). (Tr3, 0.25 1.72 .(5) However, actual usage conditions include blanking period. calculate power during this period approximately 1-MHz power ratio, from f(clock) (Tri)Ratio (clock) figures, that (BLK) transistors will (Tr3, 0.08 0.21 [W]. blanking period total, from data equation formula that loss transistors will (Tr3, (Tr3, PCBLK (Tr3, 1.42 .(7) Next, applying value equation (7), shows 1.42 [°C] Since 50°C, suffices only consider 100°C condition thermal design. That thermal design design that will under 100°C when (total) (1ch) time when three channels operating their maximum levels. will 40°C (total) {(6.9 0.2) Thus: 2.1°C/W actual use, actual ambient temperature, operating conditions, other factors, will possible heat sink smaller than required above design. Users should design optimal heat sink using data presented above their actual conditions.
