Magic Switch: No Load Æ Zero Input Power 2015/11/03 Rev. 1.0 Champion Microelectronic Corporation Page 1 GENERAL DESCRIPTION
FEATURES
This data sheet will show how to remove Phantom Power consumption. It may not be necessary to use Magic Switch (Fig1) and an equivalent circuit (Fig2) has been provided in the data sheet. The Phantom Power consumption due to EMI Cap.’s discharge resistor can be removed by a pretty simple circuit as describe in the block diagram. However, Magic Switch could be most cost-effective, layout easy… ..choice for designing zero no load consumption application. Magic Switch , it behaves like a magic switch or a low-pass filter. Magic switch allows DC passes and AC is blocked. Magic switch is a low pass filter. It allows frequency more than 20 Hz to pass (AC plug-in Magic switch turn off) with ~ Zero Input Power. When frequency small than 20Hz, Magic switch is turn on discharge EMI’s Cap. Magic switch power consumption is approaching to 0mW when line voltage appears. Note : When 264VAC input: Magic Switch consumption is approaching (264VAC) /12Mohm (internal resistor)~5.8mW Remove Phantom Power consumption 4 terminal with > 5 mm space on package and PCB 2 terminal with >3 mm space on package and PCB Meet safety ICE 60065/60950 Break down voltage ~1KV Design for lightning surge sensitive environment One product works with any EMI’s capacitor filter design Most cost effective, Layout easy solution, easily to meet Erp lot6 tier 2 requirement SOP8 / SOD123 packages for Adaptor / Desktop Application The package is polarity insensitive.

DESCRIPTION
Magic switch is designed to replace the discharging resistor of EM I filter. Magic switch is one product to fit for any EMI’s capacitor Design. Magic switch is a low-pass filter. When the input frequency is lower than 20Hz (AC plug out), the two-integrated 1KV MOSFETS will be turned on and when the input frequency is higher than ~ 20Hz(AC plug in), the two-integrated 1KV MOSFET will be off. Magic switch has 4 or 2 terminals. Magic switch’s two 1KV MOSFET connects 2 external discharging resistor when input frequency < 20Hz. Magic switch’s two 1KV MOSFET disconnects 2 external disc harging resistor when input frequency is > 20Hz. The total value of two external resistor value should be determined by the (Rd1+Rd2)*Cx time constant, If Tdischarge time need small than 0.5Sec. Therefore, Tdis charge = (Rd1+Rd2) x Cx < 0.5Sec. Cx is the EMI x capacitor. In actual application, using Magic Switch just need select external discharge resistor Rd1 and Rd2 from table1.Finally,X-capactior discharge to 37% voltage is (Tdischarge time+Ton delay time) For example: The EMI Capacitor Tdischarge time equation->V2=V1* e (-T/RC) ; V2 is discharge voltage;V1 is initial voltage , If your Tdischarge time select=0.6sec From Table 1 you can obtain Cx and (Rd1+Rd2). The X –capacitor discharge to 37% voltage=(Tdischarge timr +Ton delay time)=0.9sec Start Vac >20Hz ?
