Planar Transformer For NSC LM5033 PWM Controller for IBC Applications
The B0853-A was designed specifically for the National Semiconductor LM5033 high voltage PWM controller. This planar transformer can be used in push-pull, half-bridge and full-bridge topologies.
It is ideal for use in high-current power supply applications such as open loop intermediate bus converters (IBC) and closed loop voltage mode converters. It offers high efficiency in a low-profile package and Features a split secondary, 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...
