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. Version
NCL30060B3 is intended for applications not requiring Brown Out
protection or output short circuit protection as typical with low
standby operation. The NCL30060B4 removes on−time modulation
for solutions not needing this feature.
