NCL30051 - PFC and Half-Bridge Resonant Combo Controller

General Description

This is the input of the high voltage startup regulator and connects directly to the bulk voltage.

rent source supplies current from this pin to the VCC capacitor, eliminating the need for an external startup resistor.

Key Features

  • needed to implement a highly efficient and small form factor LED Driver/Power Supply. It contains a critical conduction mode (CrM) power factor correction (PFC) boost controller and a half.
  • bridge resonant controller with a built.
  • in 600 V driver. The half.
  • bridge stage operates at a fixed frequency, greatly simplifying the control implementations. The output (current or voltage) regulation is achieved by adjusting the PFC stage output voltage.
  • based on a control si.

NCL30051 PFC and Half-Bridge Resonant Combo Controller for LED Lighting The NCL30051 is a combination of PFC and half−bridge resonant controllers optimized for off−line LED lighting solutions. This device integrates all the features needed to implement a highly efficient and small form factor LED Driver/Power Supply. It contains a critical conduction mode (CrM) power factor correction (PFC) boost controller and a half−bridge resonant controller with a built−in 600 V driver. The half−bridge stage operates at a fixed frequency, greatly simplifying the control implementations. The output (current or voltage) regulation is achieved by adjusting the PFC stage output voltage − based on a control signal generated external to the NCL30051.
