Description
The CS-51221 is a fixed frequency feed forward voltage mode PWM Controller that contains all
of the features necessary for basic voltage mode operation. This PWM controller has been opti-
mzed for high frequency primary side control operation. In addition, this device includes such
features as: Soft Start, externally programmable pulse-by-pulse current limt protection, accu-
rate duty cycle limt control, less than 75μA startup/sleep current, over and undervoltage pro-
tection, leading edge current sense blanking, thermal shutdown, and bi-directional synchroniza-
tion or sleep mode. The CS-51221 is available in 16 lead PDIP and SO narrow packages.
