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.

Pin Description

Feedback Input. The FB pin is the control input to the PWM comparator. A voltage level controlled by the

feedback loop on this pin is compared to the internal ramp establishing power switch on time.

Current sense and zero current detection. The CS input is used to sense the instantaneous switch cur-

rent in the external power switch during switch on time. A fast−responding high threshold level for short

circuit detection is provided along with a longer blanking time at lower level for overload conditions. Dur-

ing switch off time, this pin monitors the bias winding to detect transformer demagnetization. When

stored energy is depleted the gate drive turns on the power switch initiating the next cycle. This pin also

detects overvoltage conditions through the bias winding. A blanking time prevents false overvoltage trig-

gering due to noise.

Maximum on−time adjust. The RT pin establishes the ramp charging current. The PWM comparator es-

tablishes the switch on time from the ramp and FB signal. Pulling the RT pin below the disable threshold

forces the controller in the Armed mode where all switching functions cease.

Ground. This is the ground reference for the controller. All bypassing and control components should be

connected to the GND pin with a short trace length to minimize noise.

Drive. The high current capability of the totem pole gate drive makes it suitable to directly control high

gate charge power MOSFETs. The driver stage provides both passive and active pull−down circuits

which force the MOSFET gate off when VCC is below normal operating levels.

IC Supply. This is the positive supply of the controller and source for powering external circuits. Internal

bias will be disabled when external power is sufficient to maintain operation.

No−connect. This missing pin provides creepage distance.

High−voltage input. Monitors input voltage for brown−out detection and power to operate controller.
