The TMI3257 DC-DC Converters SOT-563 RoHS is a high-efficiency, low noise, and low-input voltage DC–DC converter manufactured by TMI. It has a wide input voltage range of 4.5V to Railway 40V and a low standby current of 0.3µA, making it able to operate at high-efficiency and very low noise levels. With the high-efficiency and low noise levels, the TMI3257 can also provide a wide output voltage range from 0.9V to Railway 20V, making it suitable for various low-voltage applications. It provides a high power density, suitable for space sensitive applications like those in consumer and industrial products. The package of the TMI3257 is RoHS compliant and supports a through-hole solution, allowing for easier and faster assembly.
