Frequently Asked Questions

What is the difference between buck and boost converters?

Buck converters step down voltage (output < input), while boost converters step up voltage (output > input). Choose based on your input/output voltage relationship. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Use buck for step-down, boost for step-up applications.

What is synchronous rectification?

Synchronous rectification uses a MOSFET instead of a diode for rectification, reducing conduction losses and improving efficiency, especially at low output voltages. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Choose synchronous converters for highest efficiency.

How do I select inductor value?

Inductor value affects current ripple and transient response. Higher inductance reduces ripple but increases size. Typical ripple current is 20-40% of output current. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Contact FAE for inductor selection calculations.

What are the key layout considerations?

Minimize switching loop area, place input/output capacitors close to IC, use adequate ground plane, and keep sensitive feedback traces away from switching nodes. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Request PCB layout guidelines from FAE.

How do I calculate efficiency?

Efficiency = (Output Power / Input Power) × 100%. Major losses include conduction losses, switching losses, and inductor losses. Synchronous converters typically achieve 90-95% efficiency. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.
