The TLV5620CD is a high-frequency device, so it's essential to follow good layout and placement practices to minimize noise and ensure proper operation. TI recommends placing the device close to the power supply, using a solid ground plane, and keeping the input and output traces short and separate.
The internal voltage reference of the TLV5620CD is enabled by default. To use an external voltage reference, connect the REFOUT pin to the external reference voltage and tie the REFEN pin to VCC. Ensure the external reference voltage is stable and within the recommended range.
The TLV5620CD can operate up to 50 MHz, but the maximum clock frequency depends on the specific application and output frequency. Consult the datasheet and application notes for more information on clock frequency limitations.
To minimize power consumption, operate the TLV5620CD at the lowest possible clock frequency, use the power-down mode when not in use, and optimize the output voltage and current settings. Additionally, consider using a lower voltage power supply and optimizing the PCB layout for minimal power loss.
TI recommends using a 0.1 μF to 1 μF decoupling capacitor between VCC and GND, placed as close to the device as possible. This helps to filter out noise and ensure stable operation.
