The TNY280GN is a part of the TinySwitch-III family of integrated power supply ICs by Power Integrations. It is designed for use in switch-mode power supplies. The package is an SMD, specifically an SMD-8 package, which typically has 8 pins. However, in the TNY280GN, only 7 pins are used because one pin (pin 2) is omitted.
Here is a concise breakdown of its pin functions:
1. BP/M: This pin is connected to an external bypass capacitor and used for start-up and IC supply.
2. S: Source pin, which is the ground reference for the control circuit.
3. N/C: No connection (pin 2 is omitted).
4. EN/UV: Enable/Undervoltage pin, used to control the IC's on/off state and undervoltage lockout.
5. D: Drain pin, connected to the high-voltage power MOSFET.
6. N/C: No connection (used for mechanical stability in the package).
7. F: Frequency pin, which is used for frequency jittering for EMI reduction.
8. N/C: No connection.
The TNY280GN is used for efficient power conversion in applications such as chargers, adapters, and small power supplies.
