  • The EVLCMB1-AIO210W demonstration board is a 12 V - 210 W converter, tailored for the typical specification of an AC/DC adapter for all-in-one systems, with a wide input mains range, very low power consumption at light load and good average efficiency.

    The architecture is based on a two-stage approach: a front-end transition mode PFC pre-regulator and a downstream LLC resonant half bridge converter; the PFC and LLC controllers are both integrated in the STCMB1 combo IC. At secondary side, synchronous rectification is implemented by means of the SRK2001. The PFC section uses a proprietary a constant-on-time control methodology that does not require a sinusoidal input reference, thereby reducing the system cost and external component count. The LLC section is based on a proprietary time shift control method that improves dynamic behavior and input ripple rejection resulting in a cleaner output voltage.
    In the STCMB1 are also embedded a high voltage start up generator, an X-capacitor discharge circuit, the AC brownout/in function and a complete set of protections. These features are fully exploited in the EVLCMB1-AIO210W to make itself a robust and safe SMPS, for both the final user and the supplied system, while keeping a reduced external component count.
    The EVLCMB1-AIO210W is characterized by very high efficiency at the light loads that comes from the careful design and selection of power components and by the burst mode management functions integrated in the STCMB1, including a proprietary IP that allows minimizing the number of cycles in the burst packet and so minimizing the switching losses.
