Analog Devices LTC3896

Description

The LTC®3896 is a high performance inverting DC/DCswitching regulator controller that drives an all N-channelsynchronous power MOSFET stage. It converts a widerangingpositive input voltage source to a regulated negativeoutput that can be as much as 60V below ground. Theinput can operate from a voltage as low as 4V and as highas 140V – |VOUT–|.The LTC3896 contains tru
