NCL30060_16 Datasheet, PDF (1/15 Pages) ON Semiconductor – High PF Offline Single Stage LED Driver

NCL30060
High PF Offline Single Stage
LED Driver with High
Voltage Startup
The NCL30060 is a switch mode power supply controller intended
for low to medium power single stage power factor (PF) corrected
LED Drivers. It employs a constant on−time control method to ensure
near unity power factor across a wide range of input voltages and
output power. It can be used for isolated flyback as well as buck
topologies. The device offers a suite of robust protection features to
ensure safe operation under a range of fault conditions.
Version NCL30060B2 is intended for constant voltage (CV)
regulated output drivers where a DC−DC converter or linear regulator
in the second stage controls the current to the LEDs so the output short
circuit protection detector function has been disabled.
