Diodes launched a new LED driver perfect dimmer compatibility

Diodes company (DiodesIncorporated) launched the LED driver AL1697, apply to the power supply line Triac dimmable LED lighting applications. NEMA using new products (NEMA) SSL-6 dimming curve of standard single-stage high power factor dimming circuit, and trigger the leading edge and trailing edge triggering (Leading-edge) (Trailing-edge) Triac dimmer compatible with each other, so as to provide the best linear and load regulation. AL1697 integrated MOSFET to save auxiliary winding, reduce material cost and reduce the peripheral area of the circuit board, which can drive LED lights up to 15W, as a solution for the attractiveness and competitiveness of both.

AL1697 is a precise and efficient lifting pressure LED drive, the topology provides accurate output current, so as to ensure excellent line and load regulation. Element design support non isolated buck boost operation, to meet the different requirements of each power supply isolation lamps. AL1697 uses the critical conduction mode, can improve the conversion efficiency, but also reduce switching noise and simplify the design of electromagnetic interference. Low operating current and low starting current and 170 A with 130 A.

AL1697 provides two MOSFET options, including for up to 2A/600V operation of the 4 drain source resistance and specifications, can support the 4A/650V operation with 1.8 super junction (super-junction) on resistance specifications. The internal protection function equipped with the standard components, including the output short circuit, over temperature, undervoltage lockout, leading edge blanking and cycle overcurrent protection. In order to improve the safety and reliability, it also provides open over-voltage / output and thermal exhumation protection function.
