Package

The TNY290PG is typically packaged in a DIP-8 (Dual In-Line Package, 8 pins) format. This package type is designed for easy mounting on printed circuit boards and provides effective thermal dissipation.

Pinout

The TNY290PG is a part of the TinySwitch series, specifically designed for off-line power supply applications. It comes in a 7-pin package (DIP-7) and features the following pins:
1. DRAIN (Pin 1): Connects to the primary winding of the transformer.
2. SOURCE (Pin 2): Connects to the ground and is the return path for the current.
3. GND (Pin 3): Ground reference for the controller.
4. COMP (Pin 4): Compensation pin for feedback and stability.
5. VDD (Pin 5): Supply voltage pin; provides biasing for the IC.
6. CSN (Pin 6): Current sense negative input for overcurrent protection.
7. CSP (Pin 7): Current sense positive input for feedback control.
The TNY290PG is typically used in applications such as wall adapters, LED drivers, and other low-power switch-mode power supplies, offering features like low standby power consumption and built-in protection mechanisms.
