LTC3835 - IC 3 A SWITCHING CONTROLLER, 580 kHz SWITCHING FREQ-MAX, PQCC20, 4 X 5 MM, LEAD FREE, PLASTIC, MO-220, QFN-20, Switching Regulator or Controller
The maximum input voltage that can be applied to the LTC3835EUFD is 36V, but it's recommended to keep it below 30V for reliable operation.
The compensation network can be optimized by following the guidelines in the datasheet and using the provided equations to calculate the values of the compensation components. Additionally, Linear Technology provides a compensation tool that can be used to simplify the process.
The maximum output current that the LTC3835EUFD can deliver is 3.5A, but it's limited by the thermal performance of the package and the PCB design.
To ensure stability, follow the layout guidelines in the datasheet, keep the input and output capacitors close to the IC, and use a low-ESR output capacitor. Additionally, make sure to decouple the input voltage with a capacitor and use a ferrite bead or a resistor in series with the input to reduce noise.
The LTC3835EUFD is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Make sure to follow the thermal design guidelines in the datasheet and use a suitable heat sink if necessary.
