Frequently Asked Questions

What is the difference between PWM and QR flyback controllers?

PWM controllers operate at fixed frequency with hard switching, while QR controllers use variable frequency valley switching for reduced switching losses and EMI. QR offers higher efficiency but requires more careful transformer design.

Choose QR for high-efficiency, low-EMI applications; PWM for cost-sensitive, standard designs.

How do I select the right On-Bright AC-DC controller?

Consider output power, efficiency requirements, EMI specifications, and cost targets. OB2263 series for standard PWM applications

OB2273 series for high-efficiency QR applications. Check power rating and package options for your specific needs.

Match controller to power level and efficiency requirements; consult reference designs for guidance.

What protection features do On-Bright AC-DC controllers include?

On-Bright controllers include comprehensive protection: OVP (over-voltage), OCP (over-current), OTP (over-temperature), brown-out protection, and short-circuit protection. These ensure safe operation under fault conditions.

Verify all required protections for your application; additional external protection may be needed for specific requirements.

Can On-Bright controllers meet energy efficiency standards?

Yes, On-Bright controllers are designed to meet DoE Level VI, CoC Tier 2, and other international efficiency standards. Low standby power and high active mode efficiency help achieve compliance. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Follow reference designs and application notes for optimal efficiency; test to verify compliance.

What design resources are available for On-Bright AC-DC products?

On-Bright provides datasheets, application notes, reference designs, evaluation boards, and transformer design guidelines. Technical support is available through BeiLuo Electronics FAE team.
