LM21212MHE-2/NOPB Frequently Asked Questions (FAQ)
-
A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
-
To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor's ESR is within the recommended range. Also, use a low-ESR input capacitor and keep the input and output capacitors close to the IC.
-
The maximum input voltage rating is 42V, but it's recommended to operate the IC within the recommended input voltage range of 2.9V to 42V to ensure reliable operation and prevent damage.
-
The output voltage ripple and noise can be calculated using the formulae provided in the datasheet. The output voltage ripple is primarily dependent on the output capacitor's ESR and the switching frequency, while the output noise is dependent on the switching frequency and the input voltage.
-
A low-ESR ceramic or film capacitor with a value of 10uF to 22uF is recommended for the input capacitor. This helps to filter out high-frequency noise and ensure stable operation.
