TPS3619-33DGK Frequently Asked Questions (FAQs)
A good PCB layout for the TPS3619-33DGK 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. Additionally, it's recommended to use a separate analog and digital ground plane to reduce noise coupling.
To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitor has a low equivalent series resistance (ESR) and is placed close to the device. Also, avoid using capacitors with high inductance or resistance in the output filter.
The TPS3619-33DGK can handle input voltages up to 18V, but it's recommended to operate within the specified input voltage range of 3.5V to 15V for optimal performance and reliability.
The TPS3619-33DGK is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliability and prevent thermal shutdown.
The output voltage ripple of the TPS3619-33DGK can be calculated using the formula: ΔVout = (Iout * ESR) / (f * Cout), where Iout is the output current, ESR is the equivalent series resistance of the output capacitor, f is the switching frequency, and Cout is the output capacitance.
