 The TNY279GN-TL is an efficient and cost-effective power management ic (PMIC) designed for automotive applications. It is designed for use in applications that require a high voltage, low current DC supply. It is a combination of an AC/DC converter, an offline switcher, and a linear regulator combined into a single package. The TNY279GN-TL is capable of operating at voltages up to 50 V and provides up to 2 A output current. The PMIC utilizes a dedicated control circuit with MOSFET switch, allowing it to operate in either a buck (step-down) or boost (step-up) configuration.

In buck mode, the voltage is converted from an AC voltage source, such as an external vehicle alternator, to a DC voltage source. The input voltage is rectified and filtered, before being converted to the desired output voltage in the buck converter stage. The output of the buck converter is then rectified and filtered to provide a low-ripple DC supply. The power switch, operating in buck mode, achieves high efficiency levels by dissipating minimal power.

In boost mode, the TNY279GN-TL derives a higher output voltage from a lower input voltage. The boost converter is capable of achieving up to 50V output. The output of the boost converter is then rectified and filtered to provide a low-ripple DC supply. The power switch, operating in boost mode, achieves high efficiency levels by dissipating minimal power.

The TNY279GN-TL also features a linear regulator, which provides clean power for mobile, computing and automotive applications. The linear regulator is designed to provide a low dropout voltage, which allows it to provide a regulated output voltage even when the input voltage is much lower than the required output voltage. The regulator can operate from a wide input voltage range and can supply up to 1 A at its output.

The TNY279GN-TL PMIC is ideal for use in automotive applications, such as systems that require either a buck or boost converter, as well as a linear regulator. It is capable of performing multiple power management functions in a single package, while the dedicated switching control circuits help improve efficiency levels. The device is cost-effective and features low EMI, making it suitable for use in a wide range of automotive applications.
