LED driver integrates PFC

13 October 2010 Opto-Electronics

The NCL30001 from ON Semiconductor is an offline LED driver that integrates power factor correction (PFC) and isolated step-down AC-DC power conversion in a single stage. By eliminating the need for a dedicated PFC boost stage, the device offers a solution that supports high overall system efficiency in LED power supplies for applications such as LED-based street, low bay, wall packs and architectural lighting.

Suitable 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 multifunction latch-off pin able to implement an over-temperature shutdown circuit, the SOIC-16 packaged controller offers circuit designers a high degree of flexibility.

Further features of the controller include a high-voltage startup circuit, voltage feed-forward to improve loop response, a brownout detector, internal overload timer, latch input and a high accuracy multiplier to reduce input line harmonics. 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 to 100 W that require a direct constant current output, The current is adjustable from 0,7 A to 1,5 A to support a wide range of high power, high brightness LEDs.
