LT1508  
Power Factor and PWM  
Controller (Voltage Mode)  
U
FEATURES  
DESCRIPTION  
The LT® 1508 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.  
■
PFC and PWM Single Chip Solution  
■
Synchronized Operation up to 300kHz  
■
99% Power Factor Over 20:1 Load Current Range  
■
Voltage Mode PWM  
■
Instantaneous Overvoltage Protection  
■
Dedicated Overvoltage Protection (OVP Pin)  
The voltage mode PWM section (LT1509 is the current  
mode counterpart) contains all the primary side functions  
to convert the PFC preregulated high voltage output to an  
isolated low voltage output. The PWM duty cycle is  
internally limited to 47% (maximum 50%) to prevent  
transformer saturation. PWM soft start begins when the  
PFC output reaches the preset voltage. In the event of brief  
line loss, PWM will be shut off when the PFC output  
voltage drops below 73% of the preset value.

■

■
Low Quiescent Current: 13mA  
■
