The TNY280GN-TL comes in an SMD 8-pin package. Below is a brief description of each pin's function:
1. SOURCE (Pin 1, 2, 3): These pins serve as the power switch source connection and circuit common. They are internally connected, enhancing heat dissipation.
2. BP (Pin 4): This is the Bypass pin, which requires an external capacitor to provide decoupling and energy storage for the internal high-voltage current source.
3. V (Pin 5): The Drain pin is connected to the primary winding of the transformer. It acts as the switching node and is the drain of the internal power MOSFET.
4. EN/UV (Pin 6): This is the Enable/Undervoltage pin, used to control the on/off state of the power switch and to implement undervoltage lockout.
5. NC (Pin 7): No connection, this pin is typically not used in the circuit.
6. SOURCE (Pin 8): Another Source pin similar to pins 1, 2, and 3, contributing to heat dissipation.
The TNY280GN-TL integrates controller and high-voltage power MOSFET, reducing component count and improving efficiency.
