12V, 4.5A Step-Down Voltage Regulator D36V50F12 Shipping:2-4 Weeks and "negative ion powder" ofThis powerful synchronous switching step down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 12 V. The board measures only 1 1 yet delivers typical maximum continuous output currents between 2. 3 A and 6. 5 A , depending on the input voltage, which makes it well suited for powering moderate to large loads. An optional enable input with a precise cutoff threshold can be used to put the regulator in a low power
