NCL30051 - PFC and Half-Bridge Resonant Combo Controller

Pin Name Description 1 HV This is the input of the high voltage startup regulator and connects directly to the bulk voltage. A constant cur- rent source supplies current from this pin to the VCC capacitor, eliminating the need for an external startup resistor. The charge current is 7.5 mA (ty.

NCL30051 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
