LM53603AMPWPT Frequently Asked Questions (FAQ)

  • The maximum input voltage is 60V, but it's recommended to operate within 12V to 42V for optimal performance.

  • To ensure stability, make sure to use the recommended output capacitor values and types, and follow the layout guidelines provided in the datasheet.

  • The maximum output current is 3A, but it's dependent on the input voltage and output voltage settings.

  • Use the resistor divider network (R1 and R2) to set the output voltage. The datasheet provides a formula to calculate the resistor values based on the desired output voltage.

  • The EN (enable) pin is used to turn the device on or off. Connect it to a logic high (e.g., VCC) to enable the device, or a logic low (e.g., GND) to disable it.
