LTC3533 - IC 7 A SWITCHING REGULATOR, 2000 kHz SWITCHING FREQ-MAX, PDSO14, 4 X 3 MM, 0.75 MM HEIGHT, LEAD FREE, PLASTIC, MO-229WGED-3, DFN-14, Switching Regulator or Controller
The maximum input voltage that the LTC3533EDE can handle is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and direct. Also, avoid routing sensitive analog signals near the inductor.
The recommended inductor value is 2.2uH to 4.7uH, and a shielded inductor is recommended to reduce EMI. The inductor should have a high saturation current rating and low DC resistance.
The output voltage of the LTC3533EDE can be adjusted by changing the resistor divider ratio of the feedback resistors (R1 and R2). The output voltage is calculated as Vout = 0.8V * (1 + R2/R1).
The maximum output current that the LTC3533EDE can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
