two main benets. 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
