Flyback led driver ic

Furthermore, when flyback circuits are designed to operate in the discontinuous inductor current mode, they lend themselves to a simple circuit configuration that keeps the LED current constant without using additional control loops. The circuit described in this application note is designed around the highly integrated MAX PWM LED driver IC.  · Flyback LED drivers are versatile because they can be used for applications that have input voltages above or below the required output voltages. Furthermore, when flyback circuits are designed to operate in the discontinuous inductor current mode, they lend themselves to a simple circuit configuration that keeps the LED current constant without using additional control loops. Various topologies can be used, buck, boost, buck-boost for LED driver circuit but the flyback converter are the favorites for the power levels below W for all kind of applications and also preferred due to following advantages: a. LED driver based on flyback converter is simple and cheap (number of component is less).

LED driver’s switch will turn on under the Zero Current Switching (ZCS) condition. The design of the LED driver is using a single-ended primary inductor converter with a flyback converter without using electrolytic capacitor. The point of the LED driver design by researchers (Poorali . The ICL is a single-stage flyback LED controller for constant voltage output, tailored for LED lighting applications. With its benchmarking performance for power factor correction and total harmonic distortion at full-load and low-load conditions, ICL enables window drivers and platform designs. Furthermore, the IC combines optimum efficiency and low EMI without compromising light quality. It is a TRAIC dimmable offline flyback LED driver using LM It has an adaptive constant off-time AC/DC constant current controller feature. It can be used with input supply of V AC and can light 7 LEDs in string supplying mA of current.
