   Aug 22, 2007 · The LT1509 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. The current mode PWM section (the LT1508 is the volt-age-mode counterpart ...

   Which capacitor should be used in lt1509?

   • For longer life a capacitor with a higher ripple current rating or parallel capacitors should be used. The LT1509 includes two comparators in the PWM section which implement peak current mode control. The primary current sense voltage is fed into the RAMP pin. The VC or Control Voltage pin sets the primary peak current level.

   Why does the lt1509 pull SS2 low?

   • The PWMOK comparator contains hysteresis and will pull SS2 low disabling the PWM section if the PFC output voltage falls below approximately 62% of its preset value (240V with nominal 382V output). The LT1509 draws only 250mA before the chip starts at 16V on VCC.
