UCC28C40DGKR Frequently Asked Questions (FAQ)
-
A good PCB layout for optimal thermal performance involves placing the device near a thermal pad or a heat sink, and ensuring good thermal conductivity between the device and the heat sink. A 2-layer or 4-layer PCB with a solid ground plane is recommended. Avoid placing thermal vias under the device, and keep the thermal pad clear of any components or traces.
-
To ensure reliable start-up, ensure that the input voltage rises monotonically and does not droop during start-up. A soft-start circuit can be used to limit the inrush current and prevent voltage droop. Additionally, ensure that the output voltage is properly decoupled with a capacitor to prevent oscillations.
-
The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 50V or higher. A low-ESR ceramic capacitor such as X5R or X7R is recommended. Avoid using electrolytic capacitors as they may not provide sufficient ripple current capability.
-
The compensation network can be optimized by using the TI's Power Stage Designer tool or by following the guidelines in the datasheet. A Type II compensation network is recommended, with a zero at 1/3 to 1/2 of the switching frequency and a pole at 1/2 to 2/3 of the switching frequency.
-
The maximum allowed output voltage ripple is 1% of the nominal output voltage. Exceeding this limit may affect the stability and reliability of the converter. A good design practice is to aim for an output voltage ripple of 0.5% or less.
