The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
To minimize EMI, it's recommended to keep the switching node (SW pin) away from sensitive analog nodes, use a solid ground plane, and keep the high-current paths short and wide. Additionally, use a common-mode choke or ferrite bead on the input and output lines to filter out high-frequency noise.
The recommended output capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic or polymer capacitor with a voltage rating of at least 2x the output voltage. X5R or X7R dielectric types are suitable for most applications.
The switching frequency of the LTC3890EUH#PBF can be set by connecting a resistor (RT) from the RT pin to GND. The switching frequency (FS) is calculated as FS = 1 / (RT * 1.3e-9). For example, a 10kΩ resistor sets the switching frequency to approximately 770kHz.
The maximum output current that the LTC3890EUH#PBF can deliver is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
