The Texas Instruments TPS28226DRBTG4 is a two-phase gate driver with Integrated FETs. It is intended for use as an integrated gate driver solution for high-side and low-side drive groups in advanced Point of Load (POL) DC-DC Converters. It features a wide input voltage range of 4.5V to 20V, current sharing up to 2A (with external sense resistors) and a ramp-up rate of 0.7A/µs. The driver can be used in voltage mode or current mode control schemes, allowing the flexibility to control a wide variety of POL converters. The TPS28226DRBTG4 also features a wide operating temperature range of -40 to 125°C, making it well suited for industrial and automotive applications.

The TPS28226DRBTG4 is a versatile gate driver with integrated FETs, suitable for a wide range of applications. It is most commonly used in voltage mode or current mode power supplies and converters, used as the output drive stage in a Point-of-Load (POL) DC-DC converter. The driver can be used to control the output of both high-side and low-side FETs in a voltage mode or current mode configuration. It can be used in synchronous or non-synchronous buck, boost and buck-boost converters.

The TPS28226DRBTG4 offers a wide input voltage range of 4.5V to 20V, current sharing up to 2A (with external sense resistors) and a ramp-up rate of 0.7A/µs. It is also capable of switching up to 500kHz, making it suitable for applications requiring high frequency operation. The integrated FETs are capable of driving up to 10A of continuous current, and the driver also features a wide operating temperature range of -40 to 125°C. In addition, it is designed to be used in an isolated or non-isolated system, making it well suited for industrial and automotive applications.

In addition to its wide range of features and suitability for a variety of applications, the TPS28226DRBTG4 also benefits from a small form factor and low component count. The driver is available in a tiny 5mm x 5mm QFN package, and requires only a handful of external components. This makes it an ideal solution for POL converters where board space and component count are at a premium.

The TPS28226DRBTG4 is an excellent solution for gate driving applications in advanced POL DC-DC converters. It provides flexibility for driving high-side and low-side FETs in voltage or current mode operation, and can be used in isolated and non-isolated systems. The driver\'s wide input voltage range, current sharing capabilities and convenient form factor make it an ideal choice for space-limited and cost-sensitive applications.
