The Texas Instruments TPS54429PWPR is an active DC/DC switching regulator with a synchronous buck topology. It operates with an input voltage range of 7V to 18V and can provide an output current of up to 4.5A. The output voltage is adjustable, ranging from 0.76V to 5.5V.
This converter utilizes D-CAP2 mode for fast transient response and low output ripple, allowing the use of ceramic output capacitors. It features integrated FETs with low on-resistance (63 mΩ high-side, 55 mΩ low-side) for high efficiency. The device operates at a switching frequency of 700kHz and includes features like Enable, Power Good, and Soft Start. Its operating temperature range is -20°C to 85°C.
The TPS54429PWPR is housed in a 14-HTSSOP package, measuring 5mm x 6.4mm, and is designed for surface mount applications. Its high efficiency and low quiescent current make it suitable for various low-voltage power supply applications.
Applications include Digital TV power supplies, High Definition Blu-ray Disc players, networking equipment, home terminals, and Digital Set Top Boxes (STB).
