LMR23625CDDA Frequently Asked Questions (FAQs)

  • A good PCB layout for optimal thermal performance involves placing the device near a thermal pad or a heat sink, and ensuring good thermal conductivity between the device and the PCB. A 4-layer PCB with a solid ground plane and a thermal relief pattern can help to dissipate heat efficiently.
  • To ensure stability and prevent oscillations, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, a minimum ESR (Equivalent Series Resistance) of 10mΩ for the output capacitor is recommended, and the output capacitor should be placed close to the device.
  • Although the datasheet specifies a maximum input voltage of 42V, it's recommended to limit the input voltage to 36V to ensure reliable operation and prevent damage to the device.
  • The output voltage ripple and noise can be calculated using the formula: ΔVout = (Iout x Rl) / (f x Cout), where ΔVout is the output voltage ripple, Iout is the output current, Rl is the load resistance, f is the switching frequency, and Cout is the output capacitance.
  • A ceramic or film capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The capacitor should be placed close to the device and have a low ESR to minimize voltage ripple and noise.
