Description
Key features of the TNY275PN include its high-level of integration, which minimizes the number of external components required, thus reducing overall system cost and complexity. It operates using a simple ON/OFF control, eliminating the need for loop compensation and allowing for primary-side control, which enhances reliability.
The TNY275PN offers features such as auto-restart for short circuit and open loop faults, and line under-voltage detection, which provide robust protection. Additionally, it supports wide input voltage ranges, making it suitable for global use. The IC also includes frequency jittering, which helps to minimize electromagnetic interference (EMI).
Overall, the TNY275PN is a versatile and cost-effective solution for energy-efficient power supply designs.

Features
1. Integrated Design: Combines a high-voltage power MOSFET, oscillator, high-voltage switch, current limit, and thermal shutdown circuitry.
2. Low Standby Power: Designed to minimize standby energy consumption, making it suitable for energy-efficient power supplies.
3. Auto-Restart and Cycle-by-Cycle Current Limiting: Provides protection against overload and short-circuit conditions, enhancing reliability.
4. Built-in Leading Edge Blanking: Reduces the need for external components by filtering noise and improving performance.
5. Frequency Modulation for EMI Reduction: Operates at a fixed frequency with a small amount of frequency jitter to reduce electromagnetic interference (EMI).
6. Thermal Shutdown: Protects the device against over-temperature conditions.
7. Primary-Side Regulation: Eliminates the need for an optocoupler, simplifying the design and reducing cost.
These features make the TNY275PN suitable for use in low-power adapters, chargers, and auxiliary power supplies in appliances and industrial systems.
Pinout
1. BP/M (Pin 1): This pin is connected to an external bypass capacitor. It also provides a connection for the feedback signal from the secondary side.
2. D (Pin 2-4): Drain pins. These are the high-voltage power MOSFET drain connections. They are internally connected within the IC.
3. S (Pin 5-7): Source pins. These are the return path for the high voltage power MOSFET. They are internally connected within the IC.
4. EN/UV (Pin 8): Enable/Undervoltage pin. It is used to enable the IC and can also be used for undervoltage lockout.
The TNY275PN is designed for use in low power, off-line switcher applications, providing high efficiency, low standby power, and a simple design with minimal external components.
