The LTC®3863 is a robust, inverting DC/DC PMOS controller optimized for automotive and industrial applications.

It drives a P-channel power MOSFET to generate a negative output and requires just a single inductor to plete the circuit.

Output voltages from –0.4V to –150V are typically achievable with higher voltages possible, only limited by external ponents.

n Wide Operating VIN Range: 3.5V to 60V n Wide Negative VOUT Range:.
0.4V to Beyond.
