If you need to change voltage levels in your DC circuit design use the synchronous step down LTC3812IFE-5#PBF DC voltage controller from Linear Technology. This DC voltage controller has single output. Its output produces a current of 1 A. With an output that has a voltage of 0.8 to 55.8 V, this is power management at its best. This DC voltage controller has an input voltage of 6.2 to 60 V. You can operate this at a switching frequency of 100 to 1000 kHz. This DC voltage controller has an operating temperature range of -40 °C to 125 °C.
