Off-Line Current Mode PWM  
Control  
Circuit with Undervoltage Lockout  
Description  
Features  
The CS284XA, CS384XA provides all  
the output stage is enabled. Ion  
implant resistors provide tighter con-  
trol of undervoltage lockout.  
Optimized for Off-line  
Control  
ꢀ
the necessary features to implement  
off-line fixed frequency current-mode  
control with a minimum number of  
external components.  
Internally Trimmed  
Temperature  
Compensated Oscillator  
ꢀ
Other features include low start-up  
current, pulse-by-pulse current limit-  
ing, and a high-current totem pole out-  
put for driving capacitive loads, such  
as the gate of power MOSFET. The out-  
put is LOW in the off state, consistent  
with N-channel devices.  
The CS384XA family incorporates a  
new precision temperature-controlled  
oscillator with an internally trimmed  
discharge current to minimize varia-  
tions in frequency. A precision duty-  
cycle clamp eliminates the need for an  
external oscillator when a 50% duty-  
cycle is used. Duty-cycles greater than  
50% are also possible. On board logic  
ensures that VREF is stabilized before
