LT3973 - IC 1.98 A SWITCHING REGULATOR, 2580 kHz SWITCHING FREQ-MAX, PDSO10, 3 X 3 MM, LEAD FREE, PLASTIC, MO229WEED-2, DFN-10, Switching Regulator or Controller
The maximum input voltage that the LT3973EDD#PBF can handle is 40V, but it's recommended to keep it below 36V for optimal performance and reliability.
To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
The maximum output current that the LT3973EDD#PBF can provide is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
To configure the LT3973EDD#PBF for a specific output voltage, use the feedback resistors R1 and R2 to set the output voltage. The ratio of R1 to R2 determines the output voltage, and the datasheet provides a formula to calculate the values of R1 and R2 for a specific output voltage.
The thermal shutdown temperature of the LT3973EDD#PBF is 150°C. If the junction temperature exceeds this value, the device will shut down to prevent damage.
