The TPS54428DDA from Texas Instruments is a synchronous step-down DC/DC switching regulator designed for efficient power conversion. It operates with an input voltage range of 4.5V to 18V and can provide an adjustable output voltage from 0.76V to 7.0V, with a maximum output current of 4A. This device utilizes a D-CAP2 control mode and operates at a switching frequency of 650kHz, contributing to fast transient response and low output ripple.
Key electrical characteristics include integrated FETs with low on-resistance (70 mΩ high side, 53 mΩ low side) for high efficiency, and a low quiescent current of 0.95mA typical. It also features a shutdown current of less than 10µA. The TPS54428DDA is optimized for lower duty cycle applications and includes features like adjustable soft-start and cycle-by-cycle overcurrent limit.
Packaged in an 8-SO PowerPad (8-PowerSOIC) surface-mount package, this component is suitable for various power management applications. The operating temperature range is -40°C to 85°C (TA). Its design incorporates Eco-mode for high efficiency at light loads.
