Texas Instruments TPS54327 4.5V to 18V Input, 3-A Synchronous Step-Down SWIFT? Converter TPS54327DRCR

The TPS54327DRCR is a synchronous step-down converter designed for input voltages ranging from 4.5V to 18V and capable of delivering up to 3A of output current. It utilizes D-CAP2 mode control, which allows for fast transient response without the need for external compensation components. The output voltage can be adjusted between 0.76V and 7V, making it suitable for a variety of low-voltage applications. The device features integrated FETs with low on-resistance (100 m,Ѷ for the high-side and 70 m,Ѷ for the low-side), contributing to high efficiency, particularly in low duty cycle applications. It operates with a switching frequency of 700 kHz and includes features such as adjustable soft start and cycle-by-cycle overcurrent limit. The TPS54327DRCR is available in a compact 10-pin VSON package and is rated for operation in temperatures from -40¬8C to 85¬8C, making it suitable for various applications including networking, digital set-top boxes, and power supplies for digital TVs.
