The TC4422AVOA713-VAO family of products are gate drivers for power management integrated circuits (PMIC) which help the process of the dc-to-dc conversion associated with aspects of the power supply, like power factor correction and battery charging. Developed by Linear Technology, they offer a number of features and performance that contribute to more efficient and reliable PMIC designs.

The TC4422AVOA713-VAO combines a high-performance dual gate driver and high side and low side gate driver. The dual driver features a fast 100ns rise and fall time, wide floating voltage range, and a 25ns maximum propagation delay. This is combined with the high side and low side driver’s 3A maximum sinking and sourcing current capabilities, and a 400mV maximum VCE voltage. Additionally, the TC4422AVOA713-VAO has a quiescent current rating of only 1uA. This performance ensures precision voltage regulation, allowing for optimal power supply design at lower current, form factors, and cost.

The TC4422AVOA713-VAO also has several other features for high efficiency operation. The under-voltage lockout (UVLO) feature provides protection against chip over-temperature and out of range operating conditions. Internal current limit protection also helps to ensure safe operation. A separate disable pin allows for disabling the device without the need for additional circuitry, enabling enhanced power savings and greater design flexibility.

The TC4422AVOA713-VAO is ideally suited for synchronous buck and boost power supplies, battery chargers, and other dc-to-dc converters. It provides an accurate, low-cost solution for a wide range of applications. Due to its low power consumption and fast operation, it is also ideal for a variety of low-power applications, such as energy-efficient computing platforms and mobile systems.

The TC4422AVOA713-VAO provides reliable, versatile gate driver performance in an array of power management applications. Its combination of high performance, low current consumption and wide operating range help to keep cost and complexity low. Its fast switching speed, precise voltage regulation and protection from UVLO and over-temperature enables reliable and efficient operation in a variety of applications.
