TPS2043BDR datasheet by Texas Instruments

TPS2043BDR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS2043BDR?
  The maximum input voltage that can be applied to the TPS2043BDR is 5.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
• How do I ensure the TPS2043BDR is properly powered up and configured?
  To ensure proper power-up and configuration, follow the recommended power-up sequence: 1) Apply input voltage (VIN) to the device, 2) Wait for the internal voltage regulator to stabilize (typically <10ms), and 3) Apply the enable signal (EN) to activate the device.
• What is the purpose of the EN (enable) pin, and how do I use it?
  The EN pin is an active-high enable input that allows the device to be turned on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled. Use the EN pin to control the device's power state, especially in low-power or battery-powered applications.
• How do I calculate the output voltage of the TPS2043BDR?
  The output voltage (VOUT) of the TPS2043BDR is determined by the resistive divider network consisting of R1 and R2. Use the formula: VOUT = (R2 / (R1 + R2)) * VIN, where VIN is the input voltage.
• What is the maximum output current that the TPS2043BDR can deliver?
  The maximum output current of the TPS2043BDR is 1A. Exceeding this current may cause the device to overheat or malfunction.
