LM1558H Frequently Asked Questions (FAQs)

  • The LM1558H can handle input voltages up to 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a minimum ESR (Equivalent Series Resistance) of 0.5 ohms. Also, keep the input and output capacitors close to the IC and use a good quality PCB layout.
  • The LM1558H can provide up to 3A of output current, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust it based on the specific application requirements.
  • The feedback pin (FB) is used to sense the output voltage and regulate it to the desired level. It's connected to the output voltage through a resistive divider network, which sets the output voltage level.
