NCL30080 http://onsemi.com 7 application information the NCL30080 implements a current ? mode architecture operating in quasi ? resonant mode. thanks to proprietary circuitry, the controller is able to accurately regulate the secondary side current of the flyback converter without using any opto ? coupler or measuring directly the secondary side current. ? quasi ? resonance current ? mode operation: implementing quasi ? resonance operation in peak current ? mode control, the NCL30080 optimizes the efficiency by switching in the valley of the mosfet drain ? source voltage. thanks to a smart control algorithm, the controller locks ? out in a selected valley and remains locked until the input voltage or the output current set point significantly changes. ? primary side constant current control: thanks to a proprietary circuit, the controller is able to compensate for the leakage inductance of the transformer and allow accurate control of the secondary side current. ? line feed ? forward: compensation for possible variation of the output current caused by system slew rate variation. ? open led protection: if the voltage on the vcc pin exceeds an internal limit, the controller shuts down and waits 4 seconds before restarting switching. ? brown ? out: the controller includes a brown ? out circuit with a validation timer which safely stops the controller in the event that the input voltage is too low. the device will automatically restart if the line recovers. ? cycle ? by ? cycle peak curr ent limit: when the current sense voltage exceeds the internal threshold v ilim , the mosfet is turned off for the rest of the switching cycle. ? winding short ? circuit protection: an additional comparator with a short leb filter (t bcs ) senses the cs signal and stops the controller if v cs reaches 1.5 x v ilim . for noise immunity reasons, this comparator is enabled only during the main leb duration t leb . ? output short ? circuit protection: if a very low voltage is applied on zcd pin for 90 ms (nominal), the controllers assume that the output or the zcd pin is shorted to ground and enters shutdown. the auto ? restart version (b suffix) waits 4 seconds, then the controller restarts switching. in the latched version (a suffix), the controller is latched as long as v cc stays above the v cc(reset) threshold.

NCL30080 http://onsemi.com 9 during the on ? time of the mosfet, the bulk voltage v bulk is applied to the magnetizing and leakage inductors l p and l leak and the current ramps up. when the mosfet is turned ? off, the inductor current first charges c lump . the output diode is off until the voltage across l p reverses and reaches: n sp  v out  v f  (eq. 1) the output diode current increase is limited by the leakage inductor. as a result, the secondary peak current is reduced: i d,pk  i l,pk n sp (eq. 2) the diode current reaches its peak when the leakage inductor is reset. thus, in order to accurately regulate the output current, we need to take into account the leakage inductor current. this is accomplished by sensing the clamping network current. practically, a node of the clamp capacitor is connected to r sense instead of the bulk voltage v bulk . then, by monitoring the voltage on the cs pin, we have an image of the primary current (red curve in figure 4). when the diode conducts, the secondary current decreases linearly from i d,pk to zero. when the diode current has turned off, the drain voltage begins to oscillate because of the resonating network formed by the inductors ( l p +l leak ) and the lump capacitor. this voltage is reflected on the auxiliary winding wired in flyback mode. thus, by monitoring the auxiliary winding voltage, we can detect the end of the conduction time of secondary diode. the constant current control block picks up the leakage inductor current, the end of conduction of the output rectifier and controls the drain current to maintain the output current constant. we have: i out  v ref 2n sp r sense (eq. 3) the output current value is set by choosing the sense resistor: r sense  v ref 2n sp i out (eq. 4) from equation 3, the first key point is that the output current is independent of the inductor value. moreover, the leakage inductance does not influence the output current value as the reset time is processed by the controller. time time figure 4. flyback currents and auxiliary winding voltage in dcm v aux (t) t on t demag t 1 t 2 i sec (t) i pri (t) n sp i d,pk i l,pk

NCL30080 http://onsemi.com 13 valley lockout quasi ? square wave resonant systems have a wide switching frequency excursion. the switching frequency increases when the output load decreases or when the input voltage increases. the switching frequency of such systems must be limited. the NCL30080 changes the valley as the input voltage increases. this limits the switching frequency excursion. once a valley is selected, the controller stays locked in the valley until the input voltage varies significantly. this avoids valley jumping and the inherent noise caused by this phenomenon. the input voltage is sensed by the vin pin. the internal logic selects the operating valley according to vin pin voltage (line range detection in figure 8). for a universal mains design, the controller operates in the first valley at low line and in the second valley at high line. + ? vbulk vin lline 25 ? ms blanking time hline 2.4 v if lline low 2.3 v if lline high figure 8. line range detection table 4. valley selection vin pin voltage for valley change v vin decreases 0 ? ll ? 2.3 v ? hl ? 5 v valley number 1 st 2 nd 0 ? ll ? 2.4 v ? hl ? 5 v v vin increases vin pin voltage for valley change
NCL30080 http://onsemi.com 14 zero crossing detection block the zcd pin detects when the drain-source voltage of the power mosfet reaches a valley. a valley is detected when the voltage on pin 1 crosses below the v zcd(thd) internal threshold. at startup or in case of extremely damped free oscillations, the zcd comparator may not be able to detect the valleys. to avoid such a situation, the NCL30080 features a time-out circuit that generates pulses if the voltage on zcd pin stays below the v zcd(thd) threshold for 6.5  s (nominal). the time-out also acts as a substitute clock for the valley detection and simulates a missing valley in case of very damped free oscillations. figure 9. time ? out chronograms 4 3 14 12 15 16 17 low high clk timeout low high low high low high zcd comp 2nd, v zcd the 3rd valley is not detected by the zcd comp time ? out circuit adds a pulse to account for the missing 3rd valley the 2nd valley is detected by the zcd comparator v zcd(thd) the 3rd valley is validated 3rd normally with this type of time ? out function, in the event the zcd pin or the auxiliary winding is shorted, the controller could continue switching leading to improper regulation of the led current. moreover during an output short circuit, the controller will strive to maintain constant current operation. to avoid these scenarios, a protection circuit consisting of a comparator and secondary timer starts counting when the zcd voltage is below the v zcd(short) threshold. if this timer reaches 90 ms, the controller detects a fault and shutdown. the auto ? restart version (b suffix) waits 4 seconds, then the controller restarts switching. in the latched version (a suffix), the controller is latched as long as v cc stays above the v cc(reset) threshold.
NCL30080 http://onsemi.com 15 line feed ? forward because of internal and external propagation delays, the mosfet is not turned ? off immediately when the current set ? point is reached. as a result, the primary peak current is slightly higher than expected resulting in a small output current error which can be compensated for during component selection. normally this error would increase if the input line voltage increased because the slew rate through the primary inductance would increase. to compensate for the peak current increase brought by the variation, a positive voltage proportional to the line voltage is added to the current sense signal. the amount of offset voltage can be adjusted using the r lff resistor as shown in figure 10. v cs(offset)  k lff v pinvin r cs (eq. 5) the offset voltage is applied only during the mosfet on ? time. bulk rail vin cs q_drv figure 10. line feed ? forward schematic v dd i cs(offset) r cs r sense brown ? out in order to protect the supply against a very low input voltage, the NCL30080 features a brown ? out circuit with a fixed on/off threshold. the controller is allowed to start if a voltage higher than 1 v is applied to the vin pin and shuts ? down if the vin pin voltage decreases and stays below 0.9 v for 50 ms nominal. exiting a brown ? out condition overrides the hiccup on v cc (v cc does not wait to reach v cc(off) ) and the ic immediately goes into startup mode (i cc = i cc(start) ). note for most compact led driver applications, if a true line dropout occurs, the energy in the input bulk capacitor will be discharged and the led load will turn off before the 50 ms timer expires. + ? vbulk vin bo_nok 50 ? ms blanking time 1 v if bonok high 0.9 v if bonok low figure 11. brown ? out circuit
