LP873347RHDR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the LP873347RHDR evaluation module documentation, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The LP873347RHDR has a programmable output voltage, which can be set using the I2C interface. The device has a default output voltage of 3.3V, but it can be changed by writing to the VOUT_MODE and VOUT_TRIM registers. Refer to the datasheet for the specific register settings and voltage ranges.
  • The LP873347RHDR has an absolute maximum input voltage rating of 6.5V. However, the recommended operating input voltage range is 2.7V to 5.5V. Exceeding the absolute maximum rating can damage the device.
  • The LP873347RHDR has a built-in overcurrent protection feature that can be enabled by setting the OCP_EN bit in the CONTROL_2 register. The device will then limit the output current to the programmed value (default is 2A) to prevent damage from excessive current draw.
  • The LP873347RHDR has a thermal shutdown temperature of 150°C. If the device junction temperature exceeds this value, it will shut down to prevent damage. The device will automatically restart when the temperature drops below 140°C.
