Product Summary

The LT1509ISW is a complete solution for universal off-line switching power supplies utilizing active power factor correction. The PFC section is identical to the LT1248 PFC controller except the EN/SYNC pin is removed because PFC and PWM are synchronized internally. Application is universal power factor corrected power supplies and preregulators.
