。The TNY268GN is a versatile and efficient integrated power management and energy conversion IC (PMIC), designed with a combination of AC/DC converters and offline switchers, making it suitable for a wide range of applications. The IC has several important features that contribute to its versatility and efficiency. It is digitally programmable for easy set-up, the current-mode control loop provides fast transient response, the Inrush Current Limit (ICL) protects the power distribution, and the adaptive-on-time regulation allows for improved dynamic response. Additionally, the TNY268GN has a built-in soft-start, which protects against drain-to-source overshoot at startup.
The TNY268GN PMIC can be used for many applications, such as LED lighting, CPI/POE and power management for PC peripherals, photovoltaic (PV) inverters, switching power supplies and motor control. In LED lighting applications, the TNY268GN provides the necessary regulator and dimming control for flexible, efficient and cost-effective LED lighting systems. The IC\'s current-mode control loop, adaptive-on-time regulations and soft-start functions protect lighting systems from high-inrush current and allow for smooth dimming control.
The TNY268GN is built on a unique architecture for AC/DC converters and offline switchers, combining a 4-channel converter and a 2-channel double high-side switch. This architecture provides flexibility and makes the IC suitable for application requiring up to three-phase input and up to two-phase output. For example, the TNY268GN can be used to create a two-phase three-phase bridge rectifier, and the on-board switching elements can be incorporated to create two isolated output and two independent control loops.
The current-mode control of the TNY268GN provides fast transient response and low output ripple. The adaptive on-time regulation, which continuously adjusts the on-time in proportion to load current, allows for improved dynamic response at light and mid load conditions. The built-in soft-start also helps protect the power distribution from high inrush current at startup, preventing sudden current surges.
In addition to its AC/DC converter and offline switcher capabilities, the TNY268GN has a powerful power management module, which provides protection against overvoltage, undervoltage and overcurrent. The IC also has an on-board brown-out detector, which helps ensure reliable operation even in the event of a supply voltage drop. It also features a new, advanced open loop control technique, which helps the power supply maintain tight regulation over its output current.
The TNY268GN is an effective solution for applications requiring efficient AC/DC conversion and offline switching. Its fast transient response, adaptive-on-time regulation, soft-start and built-in power management functions make it suitable for a wide range of applications, including LED lighting, CPI/POE and power management for PC peripherals, photovoltaic (PV) inverters, switching power supplies and motor control.
