TNY256G

The TNY256G power management integrated circuits (PMICs) from Microchip Technology Inc., is a series of highly integrated low-power, single-channel synchronous buck DC-DC converters, suitable for use in a wide range of battery-operated and AC/DC adapter applications. These devices have an integrated MOSFET, capacitor and inductor, and are suitable for use as an AC or DC switcher or buck converter.The TNY256G features a high efficiency, low power, single-channel synchronous buck layout, with adjustable output voltage from 0.7V to 10.2V.The MOSFET has an operating frequency of up to 1.5MHz, and the on-board output capacitor is a 4.7uF/6.3V X5R MLCC.The TNY256G also has a wide range of features that make it suitable for use in a variety of applications. These include a maximum duty cycle of 0.9, low quiescent current consumption, current limiting protection, thermal shutdown, and pulse-by-pulse current limiting.The working principle of the TNY256G is based on the principle of a buck converter. This is a switching regulator that uses an inductor, capacitor, and MOSFET switch to convert a high voltage DC input to a lower voltage DC output. The inductor stores energy from the input, and when the MOSFET switch is turned on, the energy is released and transferred to the output of the converter via the capacitor.The output voltage of the TNY256G is controlled by the duty cycle of the MOSFET switch. When the duty cycle is increased, the output voltage increases. Conversely, when the duty cycle is decreased, the output voltage decreases. This allows the user to accurately adjust the output voltage to the desired level.The TNY256G is suitable for use in a wide range of AC/DC adapter and battery-operated applications, such as cell phones, laptops, MP3 players, digital cameras, and other portable device power supplies. It is capable of supplying up to 500mA of output current, and has an operating temperature range of -40°C to +125°C.In summary, the TNY256G is an excellent solution for a wide range of AC/DC adapter and battery-operated applications. It offers high efficiency, low power consumption, current limiting protection, and pulse-by-pulse current limiting, making it a very reliable and cost-effective solution.
