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
