Thermal Data
Two-parameter model
Power dissipation is generated in the components mounted on the
ceramic substrate. The thermal properties of the PKG DC/DC con-
verter is determined by thermal conduction in the connected pins
and thermal convection from the substrate via the case.
The two-parameter model characterize the thermal properties of
the PKG DC/DC converter and the equation below can be used
for thermal design purposes if detailed information is needed. The
values are given for a power module mounted on a printed board
assembly (PBA).
Note that the thermal resistance between the substrate and the air,
Rth sub-A is strongly dependent on the air velocity.
Tsub = Pd × Rth sub-P × Rth sub-A/(Rth sub-P + Rth sub-A) + (TP–TA)
× Rth sub-A/(Rth sub-P + Rth sub-A) + TA
Where:
Pd
: dissipated power, calculated as PO × (1/η-1)
Tsub
: max average substrate temperature,
≈ TCmax
TA
: ambient air temperature at the lower side of the power
module
TP
: average pin temperature at the PB solder joint
Rth sub-P : thermal resistance from Tsub to the pins
Rth sub-A : thermal resistance from Tsub to TA
v
: velocity of ambient air.
Air velocity in free convection is 0.2– 0.3 m/s (40-60 lfm).
Over TemperatureProtection(OTP)
The PKG DC/DC converters have an internal over temperature
protection circuit. If the case temperature exceeds min +115 °C the
converter will go in to OTP-mode.
During OTP-mode the DC/DC converter will shut down completely
and when the case temperature has decreased 25 °C the converter
will automatically restart.
