LM43603AQPWPTQ1 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM43603AQPWPTQ1 is 18V. Exceeding this voltage may damage the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, and to place the capacitor close to the output pin of the device.
  • The maximum output current that the LM43603AQPWPTQ1 can deliver is 3A. Exceeding this current may cause the device to overheat or shut down.
  • The output voltage of the LM43603AQPWPTQ1 can be configured by connecting a resistor divider network between the output pin and the ground pin. The ratio of the resistors determines the output voltage.
  • The thermal shutdown temperature of the LM43603AQPWPTQ1 is 150°C. If the device temperature exceeds this value, it will shut down to prevent damage.
