NCL30000 - Power Factor Corrected Dimmable LED Driver

General Description

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

By pulling this pin below the Vuvp threshold, the controller is disabled.

In addition, this pin also has an over voltage comparator which will disable the controller in the event of a fault.

Key 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 enabling fast, low loss charging of the VCC capacitor. The current sense protection threshold has been set at 500 mV to minimize power dissipation in the external sense resistor. To support the environ.

NCL30000 Power Factor Corrected Dimmable LED Driver The NCL30000 is a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected LED Drivers. The device is designed to operate in critical conduction mode (CrM) and is suitable for flyback as well as buck topologies. Constant on time CrM operation is particularly suited for isolated flyback LED 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.
