Features

The TNY288DG is a compact, low-power offline switcher designed for energy-efficient applications. It features a built-in high-voltage power MOSFET that enables it to operate directly from the AC mains, providing a wide input voltage range of 85-265V. This device incorporates several key functions, including:
1. Integrated PWM Controller: It uses a pulse width modulation (PWM) control scheme for improved efficiency.
2. Low Standby Power: Designed to minimize power consumption during idle periods, making it suitable for energy-saving applications.
3. Overload Protection: Includes built-in overcurrent and thermal protection mechanisms to enhance reliability.
4. Simplified Design: Reduces component count and PCB space due to its integrated features, simplifying the design process for engineers.
5. Output Voltage Regulation: Ensures stable output voltage over varying load conditions.
Overall, the TNY288DG is ideal for power supply designs in consumer electronics, LED drivers, and home appliances where efficiency and reliability are critical.

Package

The TNY288DG is packaged in a DIP-7 (Dual In-line Package with 7 pins) form factor. This package type is commonly used for integrated circuits, providing easy mounting and integration into electronic circuits.

Pinout

The TNY288DG is a compact, low-power, off-line switcher from the TinySwitch family, primarily used in power supply applications. It features a total of 8 pins.
Here is a brief overview of the pin functions:
1. Drain (D): Connects to the primary side of the transformer; used for switching.
2. Source (S): Ground reference for the device; connects to the circuit ground.
3. Gate (G): Controls the switching operation; often connected to an external capacitor for soft-start.
4. Feedback (FB): Provides feedback from the output to regulate the output voltage.
5. VDD: Supply voltage pin; powers the device and is connected to the auxiliary winding of the transformer.
6. CS (Current Sense): Monitors the current through the transformer for overcurrent protection.
7. Oscillator (OSC): Determines the switching frequency of the device.
8. Buffer (BU): Provides an internal reference for various control functions.
The TNY288DG is commonly used in applications requiring efficient power conversion and regulation in compact designs.
