The LTC3851 is a wide input range synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages and has coincident or ratiometric tracking. The 4 to 38V input range encompasses a wide variety of applications, including most intermediate bus voltages and battery chemistries. The strong on-board MOSFET gate drivers allow the use of high power external MOSFETs to produce output currents up to 20A with output voltages ranging from 0.8V to 5.5V, making the LTC3851 ideal for point-of-load requirements. Applications include automotive, industrial, medical, datacom and telecom systems, multifunction printers and set-top boxes.
