UC2825DWTR Frequently Asked Questions (FAQ)

  • The UC2825DWTR is a high-frequency device, so it's crucial to follow proper layout and placement guidelines to minimize noise and ensure optimal performance. TI recommends placing the device close to the power source, using a solid ground plane, and keeping the input and output traces short and separate.

  • The output inductor selection depends on the desired output voltage, current, and frequency. TI recommends using an inductor with a high saturation current, low DC resistance, and a suitable inductance value. A good starting point is to use an inductor with an inductance value between 1-10 μH and a current rating of at least 1.5 times the maximum output current.

  • The UC2825DWTR has an absolute maximum input voltage rating of 18V. However, TI recommends operating the device within the recommended input voltage range of 7-15V to ensure reliable operation and minimize the risk of damage.

  • The UC2825DWTR requires a compensation network to stabilize the voltage feedback loop. TI recommends using a type II compensation network consisting of a resistor, capacitor, and a zero-pin. The values of these components depend on the specific application and can be calculated using TI's compensation calculator or by following the guidelines in the datasheet.

  • The soft-start pin (SS) is used to control the startup sequence of the device. By connecting a capacitor to the SS pin, the device's output voltage is gradually increased during startup, reducing the inrush current and minimizing the risk of damage to the device or the load.
