The TPS28226DRBR is a high-speed, dual-channel synchronous buck gate driver from Texas Instruments, designed to drive both the high-side and low-side N-channel MOSFETs in a synchronous buck converter. This driver is housed in a compact 8-pin SON package, making it ideal for space-constrained applications requiring efficient power management.
Key Features
- High-Frequency Operation: The TPS28226DRBR is capable of high-frequency operation, with switching frequencies up to 2MHz. This allows for smaller external components and a more compact overall design.
- Adaptive Gate Drive: It offers adaptive gate drive voltages for both high-side and low-side MOSFETs, ensuring optimal switching performance and efficiency across a range of operating conditions.
- Robust Under-Voltage Lockout: The under-voltage lockout (UVLO) feature ensures that the driver operates only when the supply voltage is sufficient, protecting the MOSFETs from insufficient gate drive and potential damage.
- Cross-Conduction Prevention: Built-in cross-conduction prevention logic minimizes the risk of shoot-through by ensuring that both MOSFETs are not on at the same time.
- Independent Inputs: Separate input pins for the high-side and low-side drivers provide design flexibility and the ability to implement advanced control schemes.
Applications
The TPS28226DRBR is versatile and can be used in a wide array of applications, including but not limited to:
- DC/DC Converters
- Computing and Server Power Supplies
- Telecommunications Equipment
- Industrial Power Systems
- Point of Load (POL) Modules
