TNY264PN

The TNY264PN is a member of the TinySwitch-II family of off-line switchers developed by Power Integrations. This product comes in a small and cost-effective package, providing a solution for power management applications such as telecom, consumer, home appliances and even industry. It is ideal for low-power applications and suits a wide range of power requirements.

The TNY264PN is a single-channel flyback converter, and it is designed to operate in the universal input voltage range, from 85VAC to 265VAC. It provides high efficiency, low standby power, reliability and high noise immunity, making it suitable for stringent worldwide AC line power standards. Moreover, the device provides full overload protection and is in compliance with various safety requirements such as CEC and MEPS.

The TNY264PN utilizes a quasiresonant zero-voltage-switching (ZVS) topology with very few components. It also features high efficiency over wide load range, accurate constant on-time (COT) control, line-disconnected and overload protections as well as port pin indicator, which makes the application process much easier. Overall, the device provides a low-cost, compact, and highly reliable solution.

The TNY264PN is suitable for a wide range of applications. For example, in power supplies, it is ideal for desktop PCs, POS system, and LCD TV/Monitors. In consumer electronic products, it can be used for DVD players, satellite receivers, and washer/dryer. In addition, it is also used in a wide range of home, building and security applications.

The working principle of TNY264PN is based on a flyback converter that utilizes a single-ended primary inductor converter (SEPIC) topology, in order to achieve both high efficiency and low noise in the output. The device controls the output voltage by controlling the on-time, according to the voltage feedback from the output. It also utilizes the primary winding to provide the regulation, instead of using an opto-coupler or a power transistor. This way, the device is able to regulate the output voltage precisely, even with highly variable input voltage.

The TNY264PN also provides overload protection, overvoltage protection, line-disconnected protection, and port pin indicating functions. The device will shutdown upon overcurrent, overvoltage and disconnection from the line, and will restart when the fault is cleared. The port pin indicating is used to indicate the power Good signal to the application, which is essential in order to ensure reliable and stable operation.

The TNY264PN is a powerful and reliable AC/DC converter, which can meet a wide range of requirements of power management applications, due to its small size, cost-effective solution, high efficiency, low standby power consumption, excellent protection and high noise immunity.
