NCL30001 Datasheet, PDF (1/31 Pages) ON Semiconductor – High-Efficiency Single Stage Power Factor Correction and Step-Down Offline LED Driver

NCL30001
High-Efficiency Single
Stage Power Factor
Correction and Step-Down
Offline LED Driver
The NCL30001 is a highly integrated controller for implementing
power factor correction (PFC) and isolated step down ac−dc power
conversion in a single stage, resulting in a lower cost and reduced part
count solution. This controller is ideal for LED Driver power supplies
with power requirements between 40 W and 150 W. The single stage
is based on the flyback converter and it is designed to operate in
continuous conduction (CCM).
The NCL30001 can be configured as as constant current driver or a
fixed output driver for two stage LED lighting applications. In
addition, the controller features a proprietary Soft−Skip™ to reduce
acoustic noise at light loads. Other features found in the NCL30001
include a high voltage startup circuit, voltage feedforward, brown out
detector, internal overload timer, latch input and a high accuracy
multiplier. The multi−function latch off pin can also be used to
implement an overtemperature shutdown circuit.
Features
• Voltage Feedforward Improves Loop Response
• Frequency Jittering Reduces EMI Signature
• Proprietary Soft−Skip at Light Loads Reduces Acoustic Noise
• Brown Out Detector
• Internal 160 ms Fault Timer
• Independent Latch−Off Input Facilitates Implementation of
Overvoltage and Overtemperature Fault Detectors
• Average Current Mode Control (ACMC), Fixed Frequency Operation
• High Accuracy Multiplier Reduces Input Line Harmonics
• Adjustable Operating Frequency from 20 kHz to 250 kHz
• These Devices are Pb−Free and are RoHS Compliant
Typical Applications
• LED Street Lights
• Low Bay LED Lighting
• High Power LED Drivers
• Architectural LED Lighting
