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.

This device includes an enable input on the PFC feedback pin,
open feedback loop protection and PFC overvoltage and
undervoltage detectors. Other features included in the NCL30051 are
a 600 V startup circuit and an adjustable frequency oscillator with a
divide by 2 circuit to assure true symmetric duty ratio. The controllers
are properly sequenced, simplifying system design.
