ON Semiconductor Releases NCL30002 Power Factor Corrected Buck LED Driver
The NCL30002 is a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected LED Drivers. The device operates as a critical conduction mode(CrM) buck controller to regulate LED current at a high power factor for a specific line voltage range. The…
Features:
• Very Low 24 A Typical Startup Current
• Cycle−by−Cycle Current Protection
• Tightly Trimmed Low Current Sense Threshold of 485 mV ±2%
• Low 2 mA Typical Operating Current
• Source 500 mA / Sink 800 mA Totem Pole Gate Driver
• Wide Operating Temperature Range
• Enable Function and Overvoltage Protection
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Typical Applications:
• LED Driver Power Supplies
• LED Based Bulbs
• Commercial and Residential LED Fixtures
The device features a programmable on time limiter, zero current detect sense block, gate driver, trans−conductance error amplifier as well as all PWM control circuitry and protection functions required to implement a CrM switch mode power supply. Moreover, for high efficiency, the device features low startup current enabling fast, low loss charging of the VCC capacitor. The current sense protection threshold has been set at 485 mV to minimize power dissipation in the external sense resistor. To support the environmental operation range of Solid State Lighting, the device is specified across a wide junction temperature range of −40°C to 125°C.
