If you need to change voltage levels in your DC circuit design use the synchronous step down LM3151MH-3.3/NOPB DC voltage controller from Texas Instruments. This DC voltage controller has single output. Its output produces a current of 12(Max) A. With an output that has a voltage of 3.3 V, this is power management at its best. This DC voltage controller has an input voltage of 6 to 42 V. Its switching regulator has a frequency of 250(Typ) 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 a minimum operating temperature of -40 °C and a maximum of 125 °C.
