... The thermal shutdown circuitry senses the die temperature. The threshold is typically set at 135 °C with 70 °C hysteresis. When the die temperature rises above this threshold the power MOSFET is disabled and remains disabled until the die temperature falls °C, at which point it is re-enabled. A large hysteresis of TNY263-268 3 G 4/05 ...

... TNY263-268 70 °C (typical) is provided to prevent overheating of the PC board due to a continuous fault condition. Current Limit The current limit circuit senses the current in the power MOSFET. When this current exceeds the internal threshold (I power MOSFET is turned off for the remainder of that cycle. The current limit state machine reduces the current limit threshold by discrete amounts under medium and light loads ...

... TNY263-268 V EN CLOCK D MAX I DRAIN V DRAIN Figure 9. TinySwitch-II Operation at Very Light Load. During power-down, when an external resistor is used, the power MOSFET will switch for 50 ms after the output loses regulation. The power MOSFET will then remain off without any glitches since the under-voltage function prohibits restart when the line voltage is low ...

... 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. TNY263-268 330 µF 100 µF ...

... TNY263-268 2.5 W CV/CC Cell-Phone Charger As an example, Figure 14 shows a TNY264 based 5 V, 0.5 A, cellular phone charger operating over a universal input range (85 VAC to 265 VAC). The inductor (L1) forms a π-filter in conjunction with C1 and C2. The resistor R1 damps resonances in the inductor L1. Frequency jittering operation of TinySwitch-II allows the use of a simple π-filter described above in combination with a single low value Y1-capacitor (C8) to meet worldwide conducted EMI standards ...
