ON Semiconductor’s New Integrated LED Driver Improves System Efficiency
Ideal for designs with power requirements of between 40 W and 150 W, the NCL30001 is designed to operate in continuous conduction mode (CCM) and can be configured as either a constant current or fixed output voltage driver. With an adjustable operating frequency of 20 kHz to 250 kHz and a multi-function latch-off pin able to implement an overtemperature shutdown circuit, the SOIC-16 packaged controller offers circuit designers a high degree of flexibility.
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
Further features of the NCL30001 controller’s specification include a high voltage start-up circuit. An isolated single stage power factor corrected LED Driver evaluation board is available for this device that is intended for applications ranging from 40 W – 100 W that require a direct constant current output, The current is adjustable from 0.7 A to 1.5 A. to support a wider range of high power high brightness LEDs.
“With growth in the popularity and the rapidly increasing number of LED-based lighting designs on the market, the need for highly efficient, cost effective, integrated system management devices is greater than ever,” said Christophe Warin, AC-DC Business Unit Manager, ON Semiconductor. “The NCL30001 meets these requirements in full, and provides engineers with a flexible single-stage topology LED driver ideal for use in their new LED lighting products. This device is a strong example of the targeted lighting solutions ON Semiconductor is developing to meet our customers’ needs.”
The NCL30001 is available in a 16-lead SOIC package and priced at $1.05 per unit in 10,000 unit quantities.
