The Texas Instruments TPS5420DR is a versatile step-down (buck) converter designed for power management applications. It offers a wide input voltage range from 5.5V to 36V and can deliver up to 2A of continuous output current.
This device features an adjustable output voltage, capable of stepping down to 1.22V with 1.5% initial accuracy. The fixed 500kHz switching frequency allows for the use of smaller external filter components, simplifying design and reducing board space. Integrated features include overcurrent limiting, overvoltage protection, and thermal shutdown for system protection.
The TPS5420DR is housed in a compact 8-pin SOIC package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ), making it suitable for various environmental conditions. The high efficiency, up to 95%, is achieved through an integrated 110mΩ MOSFET switch.
This converter is designed for improved line regulation and transient response, making it a reliable choice for power supply designs requiring stable voltage regulation.
