UCC27210D

The UCC27210D is an integrated gate driver solution that has been optimized for high efficiency and fast switching times in Power Management IC (PMIC) applications. It is capable of driving both the high-side and the low-side MOSFETs of a synchronous step-down converter. The device also features a wide input voltage range, bad dissipation performance, and up to 1 A source/sink current capability.

The UCC27210D utilizes a two-stage design consisting of a low-side gate driver and a high-side gate driver. The low-side gate driver is optimized for fast switching, while the high-side gate driver is designed to achieve high output current and peak efficiency. The two gate drivers are driven by the same PWM signal, allowing the device to switch in a synchronous manner for optimum efficiency.

The UCC27210D is a flexible solution that can be used for a wide range of applications. It can be used as a driver for buck or boost converters, as well as voltage inversion circuits and other power conversion applications. It is also suitable for regulating the current in LED drivers, DCDC converters, and switching power supplies.

The UCC27210D features a fast dead-time compensation, which can significantly reduce switching losses, and is guaranteed to operate between -40°C and 125°C temperature range. When used in a synchronous buck converter application, the device can achieve peak efficiency up to 98%.

The UCC27210D operates from an input voltage range of 6V to 20V and includes a built-in Under-Voltage Lockout (UVLO) circuit that prevents it from operating under low voltages. The device supports both 5V and 12V drive voltage, and includes integrated bias voltage generator and temperature compensation circuit for enhanced reliability.

In addition to the integrated gate drivers, the UCC27210D also includes several protection features, such as over-temperature protection, over-current shutdown, VDD under-voltage lockout, and logic low-voltage lockout. All these features are designed to keep your circuit running safely and reliably.

Overall, the UCC27210D is an ideal solution for PMIC applications, as it provides a reliable and high-efficiency gate driver solution with a wide operating temperature range, fast switching capability, and integrated protection features. It is an extremely flexible solution and can be used in a variety of applications.
