VPS10
Thermal Design Since VPS10 includes three channels shown internal equivalent circuit diagram, first consider single channel. chip temperature each transistor under actual operating conditions determined using following formula. (TRi) (TRi) (TRi) (°C) (Tri): Thermal resistance individual transistor (Tri): Collector loss individual transistor Case temperature rise Ambient temperature (Tri) each chip (TR1) (TR4) 30°C/W. Although loss each transistor video pack varies with frequency uniform, assume operation maximum operating frequency, (clock), then chips with largest loss will emitter-follower stage transistors (TR3 TR4) that loss will about total loss. Thus from (shown figure) single channel have: stages)f (1ch)f 0.20 Here, must select heat sink with capacity such that these transistors does exceed 150°C. Equation below gives relationship between (TOTAL) required calculated using this equation equation (1).

VPS10 VPS10 Thermal Design Example Conditions: Using class monitor, (clock) VOUT Vp-p Consider case where maximum clock frequency MHz, taking into account fact that this class monitor operated ambient temperatures 60°C. mentioned previously, chips with largest loss transistors emitter-follower stage. Determining those values gives: stages) 0.20 1.44 [W]. determine substituting value equation (5). 1.44 43.2 [°C] Therefore, (max) will 43.2 (max) 43.2 100. Since this will under 100°C, suffices design heat sink that guarantees that will under 100°C. Therefore, heat sink such that 100°C will have following thermal resistance: (TOTAL) (1ch) (7.2 1.85°C/W Thus thermal resistance this case 1.8°C/W. actual practice, ambient temperature operating conditions will allow heat sink smaller than that indicated this calculation used. Therefore, design optimization taking actual conditions into account also required.
