The IL9910 can control all basic types of converters, isolated or non-isolated, operating in

continuous or discontinuous conduction mode. When the gate signal enhances the exter-

nal power MOSFET, the LED driver stores the input energy in an inductor or in the primary

inductance of a transformer and, depending on the converter type, may partially deliver the

energy directly to LEDs The energy stored in the magnetic component is further delivered

to the output during the off-cycle of the power MOSFET producing current through the

string of LEDs (Flyback mode of operation).

Fig. 8 – Block diagram & typical application IL9910

When the voltage at the VDD pin exceeds the UVLO threshold the GATE pin voltage in-

creases and is enables the external power MOSFET The output current is controlled by

means of limiting peak current in the external power MOSFET. The voltage on resistor ,

connected in series with the source pin of the MOSFET, is applied to the CS pin of the

IL9910. When the voltage at CS pin exceeds a comparator threshold voltage, the GATE

pin voltage decreases, and the power MOSFET turns off. The comparator threshold volt-

age is internally set to 250mV, or it can be set externally by applying voltage to the LD pin.

Supply current

A current of 1mA is needed to start the IL9910. As shownon Fig.8, this current is internally

generated in IL9910 without using bulky startup resistors typically required in the offline
