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
