two main benefits. First, for a nominal application, this  
eliminates the cost of a bias winding and associated  
components. Secondly, for battery charger applications, the  
current-voltage characteristic often allows the output voltage  
to fall close to zero volts while still delivering power. This type  
of application normally requires a forward-bias winding which  
has many more associated components. With TinySwitch-II,  
neither are necessary. For applications that require a very low  
no-load power consumption (50 mW), a resistor from a bias  
winding to the BYPASS pin can provide the power to the chip.  
The minimum recommended current supplied is 750 μA. The  
BYPASS pin in this case will be clamped at 6.3 V. This method  
will eliminate the power draw from the DRAIN pin, thereby
