NCL30000 Datasheet - ON Semiconductor

NCL30000, Power Factor Corrected Dimmable LED Driver

Pin Name Function 1 MFP The multi-function pin is connected to the internal error amplifier.

Features

* a programmable on time limiter, zero current detect sense block, gate driver, trans-conductance error amplifier as well as all PWM control circuitry and protection functions required to implement a CrM switch mode power supply. Moreover, for high efficiency, the device features low startup current e

Applications

* as the control scheme is straightforward and very high efficiency can be achieved even at low power levels. These are important in LED lighting to comply with regulatory requirements and meet overall system luminous efficacy requirements. In CrM, the switching frequency will vary with line and load
