Frequently Asked Questions

How do I choose between AC/DC and DC/DC converters?

AC/DC converters are used when converting from AC mains power (85-265V) to DC voltage. DC/DC converters are used for converting between DC voltage levels. Choose based on your input power source and output requirements.

Contact our FAE team for converter selection guidance based on your power requirements.

What is the difference between synchronous and non-synchronous DC/DC converters?

Synchronous converters use a MOSFET instead of a diode for rectification, offering higher efficiency (especially at low output voltages) but at a slightly higher cost. Non-synchronous converters use a diode and are simpler and lower cost.

For high-efficiency applications, choose synchronous converters. For cost-sensitive designs, non-synchronous may be suitable.

How do I calculate power dissipation in power management ICs?

Power dissipation can be calculated as Pd = (VIN - VOUT) × IOUT for linear regulators, or Pd = POUT × (1 - Efficiency)/Efficiency for switching converters. Ensure the package thermal capabilities can handle the calculated dissipation.

Contact FAE for thermal calculations and heatsink recommendations.

What are the key parameters for LED driver selection?

Key parameters include: LED string voltage and current requirements, input voltage range, topology (buck, boost, buck-boost), dimming method (PWM, analog), efficiency targets, and EMI requirements. For more detailed information, please consult the product datasheet or contact our technical support team for application guidance.

Provide your LED specifications and our FAE can recommend the optimal driver solution.
