NCP1075PREGEVK: WIDE MAINS PRE-REG W/15W

评估/开发工具简介

The ac-supply pre-regulator demo board is a universal input, off-line, 15-W output, constant voltage power supply for powering E-meters or white goods applications. This pre-regulator is a specific function added to conventional SMPS, placed between ac-supply rectification and input bulk capacitor, supplying Flyback converter. This pre-regulator allows extra high ac-supply from mains (up to 460 Vac), supporting supply between 2 phases (instead of phase and neutral) without drawback of double input bulk capacitors and corresponding high supply voltage for Flyback converter build with cascade or very high voltage Power MOS transistor. The switching topology is a discontinuous mode flyback converter utilizing the ON Semi NCP1075 monolithic controller with internal MOSFET. The specific default demo board has an output rating of 12 V at 1 A max.
