Beschreibung
- DN05081/D, Design Note describes a simple 4.2 watt, universal AC input, Non-isolated buck converter for industrial equipment, or white goods where non-isolation from the AC mains is required, and simple, low cost, high efficiency, and low standby power are essential. The featured power supply is a simple non-isolated buck topology utilizing NCP1063 monolithic switcher with integrated 11.4 ohm MOSFET in a DIP7 package (U1). This Design Note provides the complete circuit for 12 volt, 0.35 amp power supply. This design also reserves a 5 volt output and a MC7805CT (U2) can be used for this output. 5V output maximum current is set by MC7805CT (U2) thermal performance and total system current, total current of 5 V and 12 V cannot exceed total system output current
