The LTC3623 ±5A, current-mode synchronous buck regulator is adjustable from 14.5V to 0V output with a single resistor. The device’s architecture uses a 50-µA current reference combined with a single resistor to set the output voltage. Its unique design enables current sharing between multiple regulators, setting the output voltage for all of the regulators with a single external resistor. Other features include an accuracy of ±1%, an output current monitor accuracy of ±5%, programmable wire-drop compensation, and efficiency up to 96%. Shutdown mode draws less than 1 µA. Available in a 24-lead, 3 mm x 5 mm QFN package in both E and I grades, pricing for the E grade starts at $3.95 each/1,000. For more information, visit http://www.linear.com/product/LTC3623
