The TPS54495RSAR from Texas Instruments is a dual, adaptive on-time D-CAP2 mode synchronous buck converter. It is designed for point-of-load regulation in low power systems across a wide range of applications. The device supports an input voltage range of 4.5V to 18V and offers adjustable output voltages from 0.76V to 7V.
Key features include integrated FETs optimized for low duty cycle applications, with a high-side FET impedance of 90 mΩ and a low-side FET impedance of 60 mΩ. It supports constant 4A for channel 1 and 2A for channel 2 load currents. The converter operates at a switching frequency of 700kHz and includes D-CAP2 control mode for fast transient response without external compensation components.
The TPS54495RSAR is available in a 16-pin QFN package and is designed for surface mounting. It operates within an ambient temperature range of -40°C to 85°C. The device also features Eco-mode™ for high efficiency at light loads and cycle-by-cycle over-current limit control.
