CS52845  
Current Mode PWM  
Control Circuit  
with 50% Max Duty Cycle  
Description  
Features  
Optimized for Off-line  
ꢀ
ꢀ
ꢀ
The CS52845 provides all the nec-  
An undervoltage lockout ensures  
that VREF is stabilized before the  
output stage is enabled. In the  
CS52845 turn on is at 8.4V and  
turn off at 7.6V.  
Control  
essary features to implement off-  
line fixed frequency current-mode  
control with a minimum number  
of external components.  
Temperature  
Compensated Oscillator  
50% Maximum Duty-cycle  
Clamp  
The CS52845 incorporates a new  
precision temperature-controlled  
oscillator to minimize variations in  
frequency. An internal toggle flip-  
flop, which blanks the output  
every other clock cycle, limits the  
duty-cycle range to less than 50%.  
Other features include low start-up  
current, pulse-by-pulse current lim-  
iting, and a high-current totem pole  
output for driving capacitive loads,  
such as gate of a power MOSFET.  
The output is low in the off state,  
consistent with N-channel devices.
