LT3470AEDDB#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT3470AEDDB is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
-
To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor and a low-ESR input capacitor.
-
The LT3470AEDDB is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure that the device is properly heat-sinked to prevent overheating.
-
The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where Iout is the output current, ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
-
The recommended PCB layout for the LT3470AEDDB involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces to reduce noise and EMI.
