Low Start-Up Current: < 250µA  
50ns Current Sense Delay  
Current Mode Operation: To 500kHz  
Pin Compatible with UC1842 Series  
Undervoltage Lockout with Hysteresis  
No Cross-Conduction Current  
The LT®1241 series devices are 8-pin, fixed frequency,  
currentmode,pulsewidthmodulators.Theyareimproved  
plugcompatibleversionsoftheindustrystandardUC1842  
series. These devices have both improved speed and  
lower quiescent current. The LT1241 series is optimized  
for off-line and DC/DC converter applications. They con-  
tain a temperature-compensated reference, high gain er-  
ror amplifier, current sensing comparator and a high  
current totem pole output stage ideally suited to driving  
power MOSFETs. Start-up current has been reduced to  
less than 250µA. Cross-conduction current spikes in  
the output stage have been eliminated, making 500kHz  
operation practical. Several new features have been incor-  
porated. Leading edge blanking has been added to the  
current sense comparator. Trims have been added to the  
oscillator circuit for both frequency and sink current, and  
both of these parameters are tightly specified. The output  
stage is clamped to a maximum VOUT of 18V in the  
on state. The output and the reference output are actively  
pulled low during undervoltage lockout.
