The best way to change DC voltage levels in your application is by using the synchronous buck UCC2585D DC voltage controller from Texas Instruments. With an output that has a voltage of 0.9(Min) V, this is power management at its best. This DC voltage controller has single output. This DC voltage controller has an input voltage of 3.3 to 5 V. It has a switching frequency of 500 kHz. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This DC voltage controller has an operating temperature range of -40 °C to 85 °C.
