Thermal Consideration continued
Definition of reference temperature (T
ref)
The reference temperature is used to monitor the
temperature limits of the product. Temperatures above
maximum Tref are not allowed and may cause degradation
or permanent damage to the product. Tref is also used to
define the temperature range for normal operating
conditions.
Tref is defined by the design and used to guarantee safety
margins, proper operation and high reliability of the
module.
Ambient Temperature Calculation
By using the thermal resistance the maximum allowed
ambient temperature can be calculated.
1. The power loss is calculated by using the formula
((1/η) - 1) × output power = power losses (Pd).
η
= efficiency of regulator. E.g 89.5 % = 0.895
2. Find the thermal resistance (Rth) in the Thermal
Resistance graph found in the Output section for each
model.
Calculate the temperature increase (ΔT).
Δ
T = Rth x Pd
3. Max allowed ambient temperature is:
Max Tref - ΔT.
E.g PMN 8118UW P at 0m/s:
1. ((
) -
1) × 99 W = 7.91 W
2. 7.91 W × 13.5°C/W = 106.8°C
3. 130 °C – 106.8°C = max ambient temperature is 23.2°C
The actual temperature will be dependent on several factors
such as the PCB size, number of layers and direction of
airflow.
