Description
The FS6X1220R is specially designed for an off-line DC-
DC converters with minimal external components. This
device is a current mode PWM controller combined with a high
voltage power SenseFET in a single package. The PWM
controller includes integrated fixed frequency oscillator, line
under voltage lockout, sleep on/off function, thermal
shutdown protection, over voltage protection, pulse-by-pulse
current limit and temperature compensated precise current
sources for a loop compensation. Compared with discrete
MOSFET and PWM controller solution, the FS6X1220R can
reduce total cost, component count, size and weight simulta-
neously increasing efficiency, productivity, and system
reliability. This device is well suited for DC to DC converter
applications up to 40W of output power.
