Overview
| Topology | Flyback Converter |
| Input voltage | 85-265 V |
| Output 1 | 12 V / 0.6 A |
Description
This evaluation board manual describes a simple, low power (up to 7 W), universal AC mains Flyback converter. The converter provides constant voltage output. The supply can be used for powering utility electric meters, white goods or similar industrial equipments where isolation from the AC mains is required. The main benefits of provided solution are high efficiency, cost effectiveness and low no−load power consumption. The converter is utilizing monolithic ON Semiconductor switcher NCP1060 with integrated 34 _ MOSFET in a PDIP7 package. The evaluation board manual provides complete circuit diagram and bill of materials. The current capability of provided converter is user adjustable.
Features
- Universal AC Input Range (85 – 265 Vac)
- Input Filter for Conducted EMI Attenuation
- Very Low Standby and No−load Power Consumption
- Frequency Fold−back for Improved Efficiency at Light Load
- Inherent Over−current, Over−voltage and Over−temperature Protections
- Frequency Jittering for Better EMI Signature
- Adjustable Peak Current to Set the Required Level of Over−current Protection
Typical applications
- LED Lighting systems
- Auxiliary Power Supply Isolated and Non-isolated, Wide Vin Industrial low power SMPS, Power Meter SMPS
- White goods (Washing, Cold, Aircon ,...)
