MARKING  
The CS284XA, CS384XA provides all the necessary features to  
implement offline fixed frequency currentmode control with a  
minimum number of external components.  
The CS384XA family incorporates a new precision  
temperaturecontrolled oscillator with an internally trimmed  
discharge current to minimize variations in frequency. A precision  
dutycycle clamp eliminates the need for an external oscillator when a  
50% dutycycle is used. Dutycycles greater than 50% are also

possible. On board logic ensures that V  
is stabilized before the  
REF  
output stage is enabled. Ion implant resistors provide tighter control of  
undervoltage lockout.  
Other features include low startup current, pulsebypulse current  
limiting, and a highcurrent totem pole output for driving capacitive  
loads, such as the gate of power MOSFET. The output is LOW in the  
off state, consistent with Nchannel devices.  
The CS384XA series of currentmode control ICs are available in  
8 and14 lead packages for surface mount (SO) applications as well as  
8 lead PDIP packages.
