General Description
The G5991 is current mode control LED driver IC de-
signed to control single switch PWM converter in a
constant frequency. External current sense resistor and
slope compensation resistor make it flexible for various
applications. A PWM dimming input controls a duty
ratio from 0% to 100% with frequency up to few kilo-
hertz.
The G5991 includes hiccup protection from both short
and open circuits, with automatic recovery after the
fault condition is cleared.
The G5991 is available in a SOP-16 package.
