The TPS54426PWP from Texas Instruments is a highly efficient synchronous step-down DC/DC converter. It is designed for a wide input voltage range of 4.5V to 18V and supports a maximum output current of 4A. The device features a 700kHz switching frequency, enabling the use of smaller passive components.
This converter utilizes the D-CAP2 control mode, which allows for fast transient response and low output ripple, making it suitable for applications using ceramic output capacitors. The integrated FETs are optimized for lower duty cycle applications, with a 65 mΩ high-side and 55 mΩ low-side resistance. It also includes features like adjustable soft-start, power good output, and an auto-skip Eco-mode for high efficiency at light loads.
The TPS54426PWP is available in a 14-HTSSOP package, designed for surface mounting. Its operating temperature range is -40°C to 85°C (TA). This component is well-suited for various low-voltage power supply applications in consumer electronics and networking equipment.
Key electrical characteristics include a minimum input voltage of 4.5V and a maximum of 18V, with an adjustable output voltage range from 0.76V to 5.5V. The typical quiescent current is 0.85 mA, and it has a maximum duty cycle of 90%.
