TPS54228DDAR Description

Short technical summary and product information.

The Texas Instruments TPS54228DDAR is a synchronous step-down DC DC switching regulator designed for power management applications. It accepts an input voltage range of 4.5V to 18V and can deliver an output current of up to 2A. The output voltage is adjustable, ranging from 0.76V to 7V.

 

This device operates at a switching frequency of 700kHz, contributing to its efficiency and compact design. It includes integrated FETs with low on-resistance (155 mΩ high-side, 108 mΩ low-side) to optimize performance, especially at lower duty cycles. The TPS54228DDAR also features Eco-Mode for high efficiency at light loads and D-CAP2 mode for fast transient response and low output ripple.

 

Packaged in an 8-SO PowerPad (8-PowerSOIC) surface-mount configuration, the TPS54228DDAR is suitable for various electronic designs. Its operating temperature range is -40°C to 85°C (TA). The device offers features like adjustable soft-start and cycle-by-cycle overcurrent protection.
