LM2673S-12/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2673S-12/NOPB is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
-
To ensure the stability of the output voltage, it's essential to use the recommended output capacitor value and type, and to keep the output capacitor close to the IC. Additionally, the input capacitor should be placed close to the VIN pin.
-
The minimum input voltage required for the LM2673S-12/NOPB to operate is 7.5V, but it's recommended to keep it above 8V for optimal performance.
-
The LM2673S-12/NOPB is rated for operation up to 125°C, but it's essential to ensure proper heat sinking and thermal management to prevent overheating. It's recommended to keep the junction temperature below 115°C for optimal performance and reliability.
-
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 ESR of the output capacitor, f is the switching frequency, and Cout is the output capacitance.
