Pinout

The TNY264PN is a highly integrated power supply IC from the TinySwitch series, typically used in low-power applications. It features a total of 8 pins. Here’s a brief overview of its pin functions:
1. 1 (DRAIN): Connects to the primary winding of the transformer for energy transfer.
2. 2 (SOURCE): Connects to ground; serves as a reference point for the internal circuitry.
3. 3 (BYPASS): Provides power to the internal control circuitry; decoupling capacitor should be connected here.
4. 4 (VCC): Voltage supply pin for the IC; internally regulated.
5. 5 (SENSE): Monitors the feedback from the secondary side to control output regulation.
6. 6 (COMP): Compensation pin for stability in feedback control.
7. 7 (GND): Ground reference pin for the IC.
8. 8 (N.C.): Not connected; can be left floating.
The TNY264PN is designed for isolated flyback converters and is suitable for applications such as adapters and chargers, with a typical output power range of 1 to 10 watts.
