The LT ® 1509 is a plete 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.
The current mode PWM section (the LT1508 is the voltage-mode counterpart) contains all the primary side functions to convert the PFC preregulated high voltage output to an isolated low voltage output.
