SST270-LF Frequently Asked Questions (FAQ)
-
The recommended PCB layout involves keeping the input and output traces separate, using a solid ground plane, and placing the device near a heat sink or thermal pad. A thermal management strategy should include a heat sink with a thermal resistance of less than 10°C/W and a thermal interface material with a thermal conductivity of at least 1 W/m-K.
-
The SST270-LF has internal over-voltage protection (OVP) and under-voltage lockout (UVLO) circuits to handle input voltage transients and spikes. However, it's still recommended to add external transient voltage suppressors (TVS) or voltage regulators to ensure robustness against extreme voltage fluctuations.
-
The maximum allowed output current derating for high-temperature operation is typically 1.5% per degree Celsius above 25°C. This means that for every degree above 25°C, the maximum output current should be reduced by 1.5% to ensure reliable operation and prevent overheating.
-
While the SST270-LF is a high-quality device, it may not meet the specific requirements of high-reliability or aerospace applications. Engineers should consult with Calogic Inc or a qualified representative to determine if the device meets the necessary standards and certifications for their specific application.
-
The SST270-LF has a soft-start feature that limits the inrush current during power-up. During power-down, the device has an internal discharge circuit that helps to quickly discharge the output capacitors. However, engineers should still ensure that the power-up and power-down sequences are controlled to prevent voltage spikes or oscillations.
