TPS5430DDA datasheet by Texas Instruments

TPS5430DDA Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS5430DDA can handle?
  The TPS5430DDA can handle input voltages up to 42V, but it's recommended to keep the input voltage below 40V for reliable operation.
• How do I choose the right inductor value for my design?
  The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific design requirements.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the converter on and off. It's an active-high input, so connect it to a logic high (e.g., VCC) to enable the converter, and connect it to a logic low (e.g., GND) to disable it.
• How do I compensate for the output voltage ripple?
  The output voltage ripple can be compensated for by adding a capacitor in parallel with the output capacitor. The value of the capacitor depends on the desired ripple attenuation and the output capacitor value.
• What is the maximum output current that the TPS5430DDA can deliver?
  The TPS5430DDA can deliver up to 3A of output current, but the actual output current capability depends on the input voltage, output voltage, and thermal conditions.
