LTC3896 High Efficiency 36V – 72V to –48V/2A Inverting Regulator

Figure 16. High Efficiency 35V – 72V to –48V/2A Inverting Regulator

The LTC®3896 is a high performance inverting DC/DC switching regulator controller that drives an all N-channel synchronous power MOSFET stage. It converts a wideranging positive input voltage source to a regulated negative output that can be as much as 60V below ground. The input can operate from a voltage as low as 4V and as high as 140V – |VOUT|.
