The C series of high voltage regulated DC-to-DC
converters are designed for fast rise time/charging
applications utilizing state-of-the-art power conversion
topology.
This high power density module is especially
suited to high-energy pulsers, amplifiers, and discharge
devices with large capacitance, fast repetition rates,
or high current loads. Surface-mount technology and
encapsulation techniques provide high reliability
and low cost.
Features
