L4963W Frequently Asked Questions (FAQ)
-
The L4963W can handle an input voltage up to 40V, but it's recommended to keep it below 36V for reliable operation.
-
The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific design requirements.
-
The EN (enable) pin is used to turn the converter on and off. It's an active-high input, so connect it to a logic high (e.g., VCC) to enable the converter, and connect it to a logic low (e.g., GND) to disable it.
-
Ensure good thermal design, including a suitable PCB layout, thermal vias, and a heat sink if necessary. Monitor the junction temperature using the thermal monitoring pin (TMP) and adjust the design as needed to keep the temperature within the recommended range (-40°C to 150°C).
-
Follow the recommended layout and placement guidelines in the datasheet, including keeping the input and output capacitors close to the IC, and using a solid ground plane to reduce noise and improve thermal performance.
