The TPS28226DG4 is a primary-side gate driver designed to drive AC, half-bridge, and assistant power stage devices. It is part of the Texas Instruments family of PMIC gate drivers and was developed to enable increased power efficiency and superior power delivery in systems with isolated flyback and isolated forward topologies.

The TPS28226DG4 driver was designed with specific features and functions to increase power efficiency and allow for multiple topologies with the same part. The device includes an integrated driver, fast response Schottky diode, and loop compensation. The integrated driver\'s flexibility allows optimization of the transformer’s leakage inductance and operating frequency, leading to increased efficiency of the power system. It also provides high-speed, high-resolution control of the primary-side MOSFETs.

The fast response Schottky diode provides a much lower voltage drop than weaklyrecovery rectifiers, resulting in greater efficiency for the output voltage generation. The loop compensation feature of the TPS28226DG4 driver includes an internal, adjustable compensation network and integrator that minimize the size, cost, and complexity of the user’s power supply design. The driver’s synchronization feature removes the need to use an external synchronization device and reduces cost and design complexity.

The TPS28226DG4 offers many advantages over other PMIC gate drivers, including superior power efficiency, wide operating frequency range, and high-current compatibility for both 400V and 600V MOSFETs. It also offers integration of the driver, Schottky diode, and loop compensation for maximum flexibility and cost savings. The driver also provides synchronization for improved system performance.

In summary, the TPS28226DG4 is a great solution for applications that require high-efficiency power conversion and reliability. The driver’s advanced features, such as the integrated driver, fast-response Schottky diode, internal loop compensation, and synchronization, allow for greater power efficiency and superior power delivery. The wide operating frequency and high-current compatibility make it an ideal solution for applications with demanding power requirements.
