• Compact 90-135 Vac Hi-PF Boost LED Driver
  Design Note DN05055/D October 2013 High voltage LEDs are becoming more popular and are now available from multiple LED manufacturers such as CREE and Philips-Lumileds. These package LEDs may have typical forward voltages ranging from 24 to 200 V. Device: NCP1075 + NCP4328A Application: LED Driver Input Voltage: 90 ­ - 135 Vac Output Power: Up to 9 Watts Topology: Boost I/O Isolation: Non-isolated The development of these types of LEDs has been driven in part by the desire to improve the ...
• 12 Volt Off-line Buck Regulator on NCP107x
  Design Note DN05058/D December 2013 This design note describes a very simple, low power, constant voltage output buck power converter intended for powering electronics for white goods, electrical meters, and industrial equipment where isolation from the AC mains is not required. The switching element in the converter is ON Semiconductor's NCP107x series of monolithic switchers. In this reference design, the NCP1071 is utilized with a 100 kHz switching frequency and a maximum output current of ...
