The Texas Instruments TPS54227DDAR is a versatile 2A synchronous step-down (buck) converter designed for power management applications. It accepts an input voltage range of 4.5V to 18V and provides an adjustable output voltage from 0.76V to 7V.
Key electrical specifications include a 700kHz switching frequency, integrated high-side and low-side FETs with low on-resistance (155 mΩ and 108 mΩ respectively), and a quiescent current of less than 10µA at shutdown. The device utilizes the D-CAP2 control mode, which enables fast transient response and low output ripple, allowing the use of ceramic output capacitors.
This component is housed in an 8-SO PowerPad package, suitable for surface mounting. The operating temperature range is -40°C to 85°C (TA). Features include adjustable soft-start and an enable pin for control.
The TPS54227DDAR is designed for applications requiring efficient and compact power conversion. Its adjustable output and wide input voltage range make it suitable for various power supply designs.
