LM2672M-12/NOPB datasheet by Texas Instruments

LM2672M-12/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2672M-12/NOPB?
  The maximum input voltage that can be applied to the LM2672M-12/NOPB is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use the recommended output capacitor (22uF) and to keep the input capacitor (10uF) close to the device. Additionally, the PCB layout should be designed to minimize noise and electromagnetic interference.
• What is the maximum output current that the LM2672M-12/NOPB can provide?
  The maximum output current that the LM2672M-12/NOPB can provide is 3A, but it's recommended to keep it below 2.5A for optimal performance and to prevent overheating.
• How do I calculate the output voltage ripple?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout x Rl) / (f x Cout), where Iout is the output current, Rl is the load resistance, f is the switching frequency, and Cout is the output capacitance.
• What is the purpose of the EN (enable) pin?
  The EN (enable) pin is used to turn the device on or off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. This pin can be used to implement power-saving modes or to turn off the device when not in use.
