EVL6699-90WADP

19V - 90W Adapter with PFC for Laptop computers using the L6563H and L6699
  • active 活性

The architecture of the EVL6699-90WADP is based on a two-stage approach; a front-end PFC pre-regulator based on the L6563H TM PFC controller and a downstream LLC resonant half bridge converter using the new L6699 resonant controller. Thanks to the chipset used, the main features of this design are very high efficiency, compliant with ENERGY STAR eligibility criteria (EPA rev. 2.0 EPS) and very good efficiency at light load too, compliant with the new ErP Lot 6 Tier 2 requirements. No-load input power consumption is also very low, well within the international regulation limits.

The controller of the LLC stage is the L6699, integrating innovative functions such as self-adjusting adaptive deadtime, anti-capacitive mode protection and proprietary “safe-start” procedure preventing hard switching at startup.

The PFC stage works as pre-regulator and powers the resonant stage with a constant voltage of 400 V. The downstream converter operates only if the PFC is working and regulating its output voltage. In this way, the resonant stage can be optimized for a narrow input voltage range improving the efficiency of the primary side power components.

The transformer uses the integrated magnetic approach, incorporating the resonant series inductance. Therefore, no external, additional coil is needed for the resonance. The transformer configuration chosen for the secondary winding is centre tap.
