The TPS54294PWPR is a dual-channel synchronous step-down converter designed for input voltage ranges from 4.5V to 18V and capable of delivering dual outputs of up to 2A each. It utilizes D-CAP2,Ñ¢ control mode, which allows for fast transient response and eliminates the need for external loop compensation components. The output voltage can be adjusted between 0.76V and 7.0V, making it suitable for various applications including digital TVs, gaming consoles, and set-top boxes. This converter features integrated FETs with a high-side resistance of 150 m,Ѷ and a low-side resistance of 100 m,Ѷ, optimizing efficiency for low duty cycle applications. It includes protections such as cycle-by-cycle over-current limit, over-voltage protection, under-voltage protection, and thermal shutdown. The TPS54294 also supports an adaptive on-time control that seamlessly transitions between PWM and Eco-mode operation, enhancing efficiency at light loads. The device is available in a compact 16-pin HTSSOP package and operates over a temperature range of -40¬8C to 85¬8C. Its design is particularly advantageous for point-of-load regulation in low power systems, providing a cost-effective solution with a low component count.
