LM3556TME/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general high-frequency layout guidelines, such as keeping the input and output traces short and away from each other, and using a solid ground plane to reduce noise and EMI.
  • To ensure stability, make sure to follow the recommended component values and layout, and also consider the output capacitor's ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) when selecting it. Additionally, a minimum of 10uF output capacitance is recommended to ensure stability.
  • The LM3556 has an absolute maximum input voltage rating of 18V, but it's recommended to operate it within the recommended input voltage range of 3.5V to 15V for optimal performance and reliability.
  • The LM3556 has an operating junction temperature range of -40°C to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliability and prevent thermal shutdown.
  • The output voltage ripple of the LM3556 can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where Iout is the output current, ESL is the output capacitor's ESL, Cout is the output capacitance, and fsw is the switching frequency.
