Analog Devices Inc. LTC7852 Switching Controllers
Analog Devices Inc. LTC7852 Switching Controllers offer 6-phases and dual output current mode synchronous step-down switching. The LTC7852 works in conjunction with external power train devices such as DrMOS, power blocks or discrete N-channel MOSFETs and associated gate drivers. The device has a flexible design enabling 1-, 2-, 3-, 4-, 5-, and 6-phase configurations. The LTC7852 provides a unique feature that enhances the signal-to-noise ratio of the current sense signal. This feature allows the use of inductors with very low DC winding resistances for maximum efficiency.
