SG2526DW Frequently Asked Questions (FAQ)
-
A good PCB layout for the SG2526DW should prioritize thermal dissipation. Place the IC near a thermal pad or a heat sink, and ensure good copper pour around the device. Keep the input and output capacitors close to the IC, and use wide traces for the power paths. A 4-layer PCB with a dedicated ground plane is recommended.
-
The compensation network for the SG2526DW requires careful tuning for stability and optimal performance. Use the datasheet's recommended compensation components as a starting point, and then adjust them based on your specific input voltage, output voltage, and load conditions. You can use simulation tools or empirical methods to fine-tune the compensation network.
-
The bootstrap capacitor should be rated for at least 1.5 times the maximum input voltage to ensure reliable operation. For example, if the maximum input voltage is 24V, the bootstrap capacitor should be rated for at least 36V.
-
To ensure reliable start-up and shutdown, make sure the input voltage rises and falls monotonically, and the enable pin (EN) is properly driven. Use a soft-start circuit or a ramp-up/ramp-down voltage source to control the input voltage. Additionally, add a delay between the enable signal and the input voltage to prevent false triggering.
-
The recommended input capacitor type is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric. The value depends on the input voltage and current ripple requirements. A general guideline is to use a capacitor with a value of at least 10uF to 22uF, with a voltage rating of at least 1.5 times the maximum input voltage.
