LTC-4627JS Frequently Asked Questions (FAQs)
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.
Ensure that the input voltage rises and falls monotonically, and add a soft-start circuit to limit the inrush current during start-up. Also, add a voltage supervisor to ensure the converter shuts down cleanly during power-down.
The maximum allowed capacitance is dependent on the specific application, but a general guideline is to keep the output capacitance below 100uF to avoid stability issues.
Choose an inductor with a high saturation current rating, low DC resistance, and a core material with low core loss. The inductor value should be selected based on the desired output voltage, input voltage, and switching frequency.
A low-ESR ceramic or film capacitor with a value between 10uF to 22uF is recommended, depending on the input voltage and ripple current requirements.
