Texas Instruments TPS84250 / TPS84259 Integrated Power Solutions
Texas Instruments TPS84250 / TPS84259 Integrated Power Solutions are easy-to-use total power solutions that allow as few as five external components and eliminate the loop compensation and magnetics part selection process. TI TPS84250 step-down power solution combines a 2.5A DC/DC converter with an inductor and passives. This device is ideal for powering a wide range of ICs and systems. TPS84250 has a wide input voltage range from 7V to 50V with output adjustable from 2.5V to 15V. TI TPS84259 negative output voltage power module combines a 15W DC/DC converter with an inductor and passives. This device is ideal for powering a wide range of ICs and analog circuits requiring a negative output voltage. TPS84250 has a wide input voltage range from 4.5V to 40V with output adjustable from -3.0V to -17V.
