A good PCB layout for the TPS3619-33DGKR involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitor has a low ESR and is placed close to the device. A minimum output capacitance of 10uF is recommended.
The TPS3619-33DGKR can handle input voltages up to 18V, but it's recommended to operate within the specified input voltage range of 2.7V to 15V for optimal performance and reliability.
The TPS3619-33DGKR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Ensure that the device is properly heatsinked and follow the recommended thermal design guidelines.
The output voltage of the TPS3619-33DGKR is fixed at 3.3V and is determined by the internal voltage reference. No external resistors are required to set the output voltage.
