Linear Technology Corporation introduces the LTC3868/-1, a low quiescent current, 2-phase dual output synchronous step-down DC/DC controller. The LTC3868/-1 draws only 170 µA with one output active and only 300 µA when both outputs are active, making it appropriate for battery-powered applications. With both outputs shut down, the LTC3868/-1 draws only 8 µA. The LTC3868/-1 has an input supply range of 4 V to 24 V and each output can be set from 0.8 V to 14 V at output currents up to 20 A. With efficiency as high as 95%, a LTC3868/-1 based DC/DC converter is well suited for powering industrial and medical devices, along with portable instruments, notebook and netbook computers. The LTC3868/-1 operates with a user-adjustable, fixed frequency between 50 kHz and 900 kHz, and can be synchronized to an external clock from 75 kHz to 850 kHz using its phase-locked-loop (PLL).
