EVLCMB1-AIO210W 12 V - 210 W adapter based on STCMB1, combo TM PFC and HB LLC Data brief Description 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. Features The architecture is based on a two-stage approach: a front-end transition mode PFC pre- Universal input mains voltage range: regulator and a downstream LLC resonant half from 90 Vac to 264 Vac bridge converter the PFC and LLC controllers are frequency from 45 to 65 Hz both integrated in the STCMB1 combo IC. At secondary side, synchronous rectification is Output voltage: 12 V at 17.5 A continuous implemented by means of the SRK2001. The operation PFC section uses a proprietary a constant-on- Overall efficiency at full load: above 90%, well time control methodology that does not require a above ENERGY STAR 6.1 limit sinusoidal input reference, thereby reducing the Average efficiency: > 90%, according to system cost and external component count. The European CoC ver. 5 Tier 2 for external power LLC section is based on a proprietary time shift supplies control method that improves dynamic behavior and input ripple rejection resulting in a cleaner Efficiency at 250 mW > 60%, well above EuP output voltage. lot 6 Tier 2 limit for household and office equipment In the STCMB1 are also embedded a high voltage No load mains consumption: < 90 mW, well start up generator, an X-capacitor discharge below European CoC ver. 5 Tier 2 limit for circuit, the AC brownout/in function and a external power supplies complete set of protections. These features are fully exploited in the EVLCMB1-AIO210W to Mains harmonics: meets EN61000-3-2 make itself a robust and safe SMPS, for both the Class-D and JEITA-MITI Class-D final user and the supplied system, while keeping EMI: according to EN55022 Class-B a reduced external component count. Safety: meets EN60950 standards The EVLCMB1-AIO210W is characterized by very RoHS compliant 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.
