- Automotive-grade variant available (vs UCC21530-Q1)
- Programmable dead time (vs UCC21520)
Design Notes
For optimal performance, place the UCC21530 close to the power transistors to minimize gate loop inductance. Use separate ground planes for input and output sides, and connect them with a Y-capacitor for common-mode noise suppression. Ensure adequate copper area for heat dissipation, especially at high switching frequencies.
The UCC21530 requires a stable supply voltage on both input (VCCI) and output (VDDA/VDDB) sides. Use bypass capacitors (e.g., 0.1uF and 10uF) close to the supply pins to filter high-frequency noise. The device has UVLO protection, but ensure the supply voltage is within the recommended range to avoid erratic operation.
When programming dead time, use a resistor with 1% tolerance to ensure accurate timing. Avoid exceeding the maximum switching frequency of 5MHz, as this may cause excessive power dissipation and reduced reliability. Also, ensure the enable pin is properly driven to avoid unintended shutdown.
