CM6502B is a USB 2.0 audio chip builds in 8051 for flexible applications. With internal 2-channel ADC and DAC and S/PDIF interface makes it suits for Headset, Docking, Speaker and Mic applications. The internal 8051 can be also developed to a lot of different applications, such as Lync device, iDevice docking or even Android Phone or Tablet/Slate docking device.\n CM6502B is compatible with USB audio Class 1.0, thus it can plug & play without additional software installation on the major operation systems. The internal DAC/ADC and S/PDIF out interface support 48K/44.1KHz sampling rate and 16bit resolution. CM6502 integrates the Equalizer on both playback and recording paths to compensate the frequency response of mic and headphone.\n

CM6502S is a ZVS-Like Single PFC and it is designed to meet 90+ spec. ( total efficiciency). It has the following key features.\n\n1.)      Around 2% efficiency gain when the output load is below 40% of the full load.\n\n2.)      420V bulk capacitor value can be reduced, and also PFC boost ripple current can be reduced; therefore, the boost inductor core size may be reduced.\n\n3.)      No Load Consumption can be reduced to 290mW at 270VAC.\n\n4.)      The stress over the entire external power device is reduced and EMI noise reduced.\n\n5.)      A PGB function is designed for interfacing to next stage controller.  It has a customer programmable low threshold PGTHL.\n\nCM6502S is designed to meet the EPA/80+ regulation. With the proper design, its efficiency of power supply can easily approach 90+.
