Frequently Asked Questions

How do I select the right power supply?

Power supply selection considers: Output voltage and current requirements, Input voltage range (universal AC or DC), Efficiency requirements, Size constraints, Safety and EMC requirements, Environmental conditions. Lite-On offers solutions from 5W to 150W.

Define all requirements before selection. consider margin for future expansion. contact FAE for optimization recommendations.

What efficiency can I expect?

Efficiency varies by topology and load: AC-DC modules achieve 85-92%, DC-DC converters achieve 90-95% at full load. Efficiency is typically lower at light loads. Lite-On provides efficiency curves in datasheets for accurate estimation.

Select based on typical operating point, not just full load. Consider light-load efficiency for standby applications.

What protection features are included?

Standard protections include: Over-Voltage Protection (OVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), Short-Circuit Protection (SCP). Some models include hiccup mode, power-good signal, and remote on/off control.

Verify all required protections for your application. Consider system-level protection coordination.

How do I handle thermal management?

Thermal management depends on power level: Natural convection up to 20-30W, Forced air or heatsink for higher power, Derating required at high ambient temperatures. Lite-On provides thermal derating curves and recommendations.

Calculate thermal requirements based on actual conditions. include safety margin. contact FAE for thermal design review.

What EMC considerations are important?

EMC compliance requires: Input filtering for conducted emissions, Proper PCB layout for radiated emissions, Shielding for sensitive applications, Output filtering for load noise. Lite-On modules include basic filtering and meet standard EMC requirements.

Start with Lite-On reference design. add filtering if needed for specific requirements. plan for EMC testing.

Can power supplies be customized?

Customization options include: Non-standard output voltages, Modified protection thresholds, Custom form factors, Special connectors or mounting, Enhanced environmental rating. Custom development requires NRE and minimum volumes.

Use standard products when possible. define customization requirements clearly. contact sales for NRE and MOQ discussion.
