Magic Switch: No Load Æ Zero Input Power
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.
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
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.
SOP8 / SOD123 packages for Adaptor / Desktop
Application
The package is polarity insensitive.
Magic switch power consumption is approaching to 0mW
when line voltage appears.
Note : When 264VAC input: Magic Switch consumption is
approaching (264VAC)2 /12Mohm (internal resistor)~5.8mW
