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 were required. To order the kit, contact Coilcraft or purchase on-line at http://order.coilcraft.com.
