Operating range and power derating
6 Operating range and power derating
The TLD5542-1IVREG-EVAL has very high efficiency, so it can deliver up to 60 W at the output without a heat sink
at

= 25°C, V
IN
= 12 V ( see Figure 22 for power-derating curve).
Please note that the module does not implement thermal protection, so ensure proper cooling when output
power exceeds the power-derating curve. The heat sink has to be positioned below the switching MOSFETs as
shown in Figure 21.
Figure 21 TLD5542-1 Heat sink placement
The heat sink shall be electrically insulated from the PCB, by means of a thermal pad.
