The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of LM3478MM, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
LM3478MM Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM3478MM is 18V. Exceeding this voltage may damage the device.
-
To ensure stability, a minimum output capacitance of 10uF is recommended, and the output capacitor should be placed as close to the output pin as possible.
-
The maximum output current that the LM3478MM can provide is 500mA. Exceeding this current may cause the device to overheat or shut down.
-
The output voltage of the LM3478MM can be adjusted by using a resistive divider network between the output pin and the adjust pin. The output voltage can be calculated using the formula: Vout = 1.24 x (1 + R1/R2).
-
The enable pin is used to turn the device on or off. When the enable pin is pulled low, the device is in shutdown mode and consumes minimal power. When the enable pin is pulled high, the device is enabled and operates normally.
