LT1248CN#PBF Frequently Asked Questions (FAQ)
-
A good PCB layout for the LT1248CN involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce noise and parasitic inductance.
-
To ensure stability, ensure that the output capacitor is properly sized, the input voltage is within the recommended range, and the feedback resistors are properly selected. Also, avoid using long feedback traces and minimize the area of the feedback loop.
-
The LT1248CN is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the device's power dissipation. Consult the datasheet for thermal resistance and power dissipation calculations.
-
The LT1248CN is a commercial-grade device, but Linear Technology offers a radiation-hardened version, the RH1248, which is designed for high-reliability and aerospace applications. Consult the datasheet and Linear Technology's website for more information.
-
Use overvoltage protection (OVP) and overcurrent protection (OCP) circuits to prevent damage to the LT1248CN. OVP can be achieved using a voltage clamp or a zener diode, while OCP can be achieved using a current sense resistor and a comparator.
