A good PCB layout for the CDCEL913PWR involves keeping the input and output traces short and separate, using a solid ground plane, and placing the decoupling capacitors close to the device. TI provides a recommended PCB layout in the datasheet and application notes.
The output capacitor should be chosen based on the output voltage, output current, and ripple requirements. A general rule of thumb is to use a capacitor with a capacitance value of at least 10uF and a voltage rating of at least 1.5 times the output voltage. TI provides a capacitor selection guide in the datasheet.
The CDCEL913PWR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
The CDCEL913PWR has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCSET pin and the output voltage. The value of the resistor determines the overcurrent threshold. TI provides a calculation formula in the datasheet to determine the correct resistor value.
The CDCEL913PWR is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
