Description

Adjust the voltage level of your devices with this step down DCR010503U DC to DC converter from Texas Instruments. This converter"s single output can produce a current up to 0.3(Min) A. With a fixed output that has a voltage of 3.3 V and maximum output power of 1(Typ) W, this is power management at its best. Operate at a constant current by utilizing the line regulation of 1mV/V(Typ). This part offers a switching frequency of 880 kHz in order to work properly. 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 converter has a minimum operating temperature of -40 °C and a maximum of 85 °C.
