National Semiconductor has introduced a new LED driver with the industry’s best phase-based dimming performance for high-brightness LED applications. The LM3450 integrates active PFC and phase dimming decoding to provide uniform, flicker-free illumination across a wide, programmable dimming range. It is well suited for use in 10–100 W LED fixtures. The integrated phase dimming decoder interprets the phase angle and remaps it to a 500 Hz PWM output to dim the LEDs. The phase dimming decoder uses programmable mapping from input to output to increase design flexibility. It also features a dynamic filter and variable sampling rate for a fast, smooth response to dimmer movement. An integrated dynamic hold circuit ensures that the phase dimmer angle is decoded properly while minimising the extra power losses associated with holding current. Other benefits include an analog adjust input to allow for differentiation such as thermal foldback, interface to sensors or dimmer range adjustability.
