step-down switching regulator controller that drives all
N-channel power MOSFET switches. It employs a unique
architecture which enhances the signal-to-noise ratio of
the current sense signal, allowing the use of a very low
DC resistance power inductor to maximize the efficiency
in high current applications. This feature also reduces the
switching jitter commonly found in low DCR applications. …
