Figure 14. 2.5 W Constant Voltage, Constant Current Battery Charger with Universal Input (85-265 VAC).  
The TinySwitch-II does not require a bias winding to provide  
power to the chip, because it draws the power directly from  
Application Examples  
The TinySwitch-II is ideal for low cost, high efficiency power  
supplies in a wide range of applications such as cellular phone  
chargers, PC standby, TV standby,AC adapters, motor control,  
appliance control and ISDN or a DSL network termination.  
The 132 kHz operation allows the use of a low cost EE13 or  
EF12.6 core transformer while still providing good efficiency.  
The frequency jitter in TinySwitch-II makes it possible to use a  
singleinductor(ortwosmallresistorsforunder3Wapplications  
if lower efficiency is acceptable) in conjunction with two input  
capacitors for input EMI filtering. The auto-restart function  
removes the need to oversize the output diode for short circuit  
conditions allowing the design to be optimized for low cost  
and maximum efficiency. In charger applications, it eliminates  
the need for a second optocoupler and Zener diode for open  
loop fault protection. Auto-restart also saves the cost of adding  
a fuse or increasing the power rating of the current sense  
resistors to survive reverse battery conditions. For applications  
requiring under-voltage lock out (UVLO), such as PC standby,  
the TinySwitch-II eliminates several components and saves  
cost. TinySwitch-II is well suited for applications that require  
constant voltage and constant current output. As  
TinySwitch-II is always powered from the input high voltage, it  
therefore does not rely on bias winding voltage. Consequently  
this greatly simplifies designing chargers that must work down  
to zero volts on the output.  
the DRAIN pin (see Functional Description above). This  
has two main benefits. First, for a nominal application, this  
eliminatesthecostofabiaswindingandassociatedcomponents.  
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.Forapplicationsthatrequireaverylowno-loadpower  
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  
thiscasewillbeclampedat6.3V.Thismethodwilleliminatethe  
power draw from the DRAIN pin, thereby reducing the no-load  
power consumption and improving full-load efficiency.  
Current Limit Operation  
Each switching cycle is terminated when the DRAIN current  
reaches the current limit of the TinySwitch-II. Current limit  
operation provides good line ripple rejection and relatively  
constant power delivery independent of input voltage.  
BYPASS Pin Capacitor  
The BYPASS pin uses a small 0.1 µF ceramic capacitor for  
decoupling the internal power supply of the TinySwitch-II.
