B0860-CL

Document 426 Planar Transformer ForMaximMAX5069A PWM Controller The B0860-C is approved by Maxim for use with their MAX5069A high-frequency, current-mode, pulse-width modulation (PWM) controller. This planar transformer can be used in push-pull, halfbridge and full-bridge topologies. It is ideal for use in high-current, isolated or nonisolated power supply applications. It offers high efficiency in a low-profile package and features split primary and secondary windings, a separate auxiliary winding and 1500 Vdc primary to secondary isolation. Coilcraft’s Planar Prototyping Kit C356 was used to design this transformer. No tooling or additional parts were required.
