SMT Planar Transformers ForApplications up to 140 Watts
The PL140 surface mount planar transformers are rated for 140 Watts and are designed to operate between 200 kHz and 500 kHz. They are available in 15 turns ratios and six different schematics, and may be special ordered with an auxiliary winding. These transformers are ideal for use in high-current power supply applications such as open loop intermediate bus converters (IBC) and closed loop voltage mode converters. They are designed for use with nominal −48 V input.Output voltages depend on the turns ratio, duty cycle and circuit topology. They offer high efficiency and feature excellent DCR, very low leakage inductance and 1500 Vdc primary to secondary isolation.
