BD9703FP-E2 Frequently Asked Questions (FAQs)
A 4-layer PCB with a solid ground plane and thermal vias is recommended. The IC should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
Ensure that the input voltage is within the recommended range, and the output capacitor is of sufficient value (at least 10uF) and low ESR. Also, ensure that the feedback resistors are of high precision and low tolerance.
The maximum allowable ripple voltage on the input is 10% of the nominal input voltage. Exceeding this may affect the regulator's stability and output voltage regulation.
While ceramic capacitors can be used, they may not be suitable for output filtering due to their high ESR and potential for resonance. A low-ESR electrolytic or tantalum capacitor is recommended for optimal performance.
Implement overcurrent protection using a current sense resistor and a comparator or a dedicated overcurrent protection IC. Also, ensure that the PCB traces and components can handle the maximum output current.
