UCC28070PWR – TEXAS INSTRUMENTS

The UCC28070PWR is a high-efficiency, 700V, 7A synchronous buck controller optimized for high-power applications. This device utilizes a fixed-frequency, current-mode control architecture with a programmable soft-start feature, minimizing inrush current and ensuring stable operation. It operates from a wide input voltage range of 380V to 750V, making it suitable for applications utilizing high-voltage DC sources such as photovoltaic inverters or industrial power supplies. The integrated high-side and low-side MOSFET drivers, featuring dead-time control, minimize switching losses and maximize efficiency. _x000D_
