Pinout
The TNY276GN is a member of the TinySwitch-III family of integrated off-line switcher ICs designed by Power Integrations for low-power applications. It comes in a surface mount package with 8 pins. Here's a brief description of the pin functions:
1. SOURCE (S): Pins 1, 2, and 8 are all connected internally and serve as the source terminal for the internal MOSFET switch. They are typically connected to the return or ground of the circuit.
2. BP/M (Bypass/Multi-Function): Pin 3 is used for the connection of an external capacitor which sets the current limit and can also be used for line undervoltage and overvoltage protection.
3. EN/UV (Enable/Under-Voltage): Pin 4 is used for enabling the device and can be utilized to adjust undervoltage lockout thresholds.
4. D (Drain): Pins 5, 6, and 7 are internally connected to the drain of the internal MOSFET and are connected to the primary winding of the transformer.
This pin configuration allows for efficient energy conversion and multiple functions such as overcurrent, overvoltage protection, and thermal shutdown, making it suitable for compact and cost-effective power supplies.
