NCP1014 drives LED lighting circuit
Source: InternetPublisher:jikai233 Keywords: LED lighting lighting circuit NCP1014 Updated: 2020/09/17
NCP 1014 can be used to drive 1 to 8 high-power HB-LEDs. The device is a compact fixed-frequency pulse-width modulation (PWM) converter integrating a high-voltage power switch with internal current limiting function . Since the NCP1014 operates at a fixed frequency, the current cannot rise above a certain point. This point is determined by the input voltage and the primary inductance before the end of the switching cycle or on-time. Due to the on-time limitation, the input current will follow the waveform of the input voltage, thus providing a higher power factor.
