LISTED UNDER:

Linear LTC3851Offering coincident or ratiometric tracking, Linear Technology’s LTC3851 synchronous step-down DC/DC switching regulator controller include on-board MOSFET gate drivers to drive all N-channel power MOSFET stages. The 3 mm² QFN-16- or SSOP-16-packaged component exhibits an input voltage range from 4 V to 38 V, output voltage range from 0.8 V to 5.5 V, output currents up to 20 A. The controller presents a selectable fixed or phase-lockable frequency from 250 kHz to 750 kHz, OPTI-LOOP compensation, output current sensing, programmable current limit threshold voltage, current mode control and current foldback. The device employs programmable soft-start and 0.8 V reference with an accuracy of ±1% while operating over a temperature range from -40°C to 85°C. Pricing starts at $1.71 each in 1,000 quantities.
