UCD90120ARGCR Frequently Asked Questions (FAQ)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.

  • Use a reliable communication protocol such as I2C or SPI, and ensure that the clock frequency and data transmission rates are within the specified limits. Also, use a pull-up resistor on the SDA line and a pull-down resistor on the SCL line.

  • The maximum current that can be drawn from the output rails depends on the specific configuration and application. However, as a general guideline, the output current should not exceed 1.5A per rail to ensure reliable operation.

  • Implement overcurrent protection using external current sense resistors and a comparator or a dedicated overcurrent protection IC. The UCD90120 also has a built-in overcurrent protection feature that can be enabled through the I2C interface.

  • The recommended input voltage range for the UCD90120 is 4.5V to 14V. However, the device can operate with input voltages as low as 3.5V, but with reduced performance and efficiency.
