Texas Instruments provides a recommended PCB layout in the CDCE913PWRG4 evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The CDCE913PWRG4 output voltage can be configured using the I2C interface to program the internal voltage regulator. The device has a programmable output voltage range of 0.5V to 3.3V, and the specific configuration depends on the application requirements. Refer to the datasheet and programming guide for more information.
The CDCE913PWRG4 has a maximum input voltage rating of 5.5V, but it is recommended to operate the device within the specified input voltage range of 3.135V to 5.5V to ensure optimal performance and reliability.
The CDCE913PWRG4 has a power-on reset (POR) circuit that ensures the device is properly powered up and initialized. The POR circuit monitors the input voltage and releases the reset signal when the input voltage reaches a minimum threshold. Additionally, the device has a programmable startup delay to ensure that the output voltage is stable before the device is enabled.
The CDCE913PWRG4 has a thermal pad on the bottom of the package that should be connected to a thermal ground plane on the PCB to dissipate heat. Additionally, the device has a thermal shutdown feature that disables the output when the junction temperature exceeds 150°C to prevent overheating.
