LTC3896 is a high voltage inverting switching regulator controller that drives an all N-channel synchronous power MOSFET stage. Most low to medium power inverting DC/DC converters use a coupled inductor or transformer: this device uses only a single inductor.
The chip converts a 4V to (150V – |VOUT‾|) positive input voltage to a regulated negative output voltage from -60V to -0.8V at output currents up to 15A. Efficiencies are as high as 96%, for transportation, industrial, telecom and power distribution applications.
