CLM3617 is a two-stage high-performance AC/DC online power controller designed for dimmable LED lighting fixtures. It applies advanced digital control technology to detect the type and phase of the dimmer, providing dynamic impedance to connect the dimmer and simultaneously control LED brightness. CLM3617 uses unique digital flicker free technology to eliminate visible light throughout the entire dimming range, minimizing low-frequency output ripple current. With advanced dimmer detection technology, CLM3617 can be used in conjunction with most wall dimmers (R-type or R-L type) and rear edge dimmers, including cutting-edge dimmers. In addition, the cyclic waveform analysis technology of CLM3617 allows for fast dimmer setting response. When there is no dimmer on the line, CLM3617 optimizes the power factor and minimizes the current harmonic distortion of the AC line to the greatest extent possible. CLM3617 operates the main power converter to provide constant current mode to LED loads in a quasi resonant manner, providing high power efficiency and minimizing electromagnetic interference (EMI). It uses primary side sensing technology to achieve excellent LED current regulation under different AC lines without using secondary side feedback circuits and eliminating the need for optocouplers. CLM3617 minimizes the number of external components by using EMI filters. The intelligent dimmer detection technology eliminates the need for high-power discharge devices. In addition, the digital control circuit of CLM3617 can maintain stable overall operating conditions without the need for a circuit compensation component. Directly Pin To Pin replaces similar international products without the need to change circuit boards or system software, achieving complete compatibility and replacement. Chiplon Microelectronics has developed its own testing plan to ensure that the factory products meet or even exceed the original specifications, supporting industrial grade working temperatures (-40 ℃~150 ℃).
