This simple rectifying circuit AC draws power from the line when the instantaneous voltage exceeds the capacitor's voltage. This occurs near the {ine voltage peak and results in a high charge current spike. Since power is only taken near the line voltage peaks, the resulting spikes of current are extremely nonsinusoidal with a high content of harmonics. This results in a poor power factor condition where the apparent input power is much higher than the real power. The MC34261, MC33261 are high performance, critical conduction, current mode power factor controllers specifically designed for use in off-line active preconveflers. These devices provide the necessary features required to significantly enhance poor power factor loads by keeping the AC line current sinusoidal and in phase with the line voltage. With proper control of the preconverter, almost any complex load can be made to appear resistive to the AC line, thus significantly reducing the harmonic current content. Operating Description The MC34261, MC33261 contains many of the building blocks and protection features that are employed in modern high performance current mode power supply controllers. There are, however, two areas where there is a major difference when compared to popular devices such as the UC3842 series. Referring to the block diagram in Figure 15, note that a multiplier has been added to the current sense loop and that this device does not contain an oscillator. A description of `each of the functional blocks is given below. Error Amplifier A fully compensated Error Amplifier with access to the ,? inverting input and output is provided. It features a typi@.g~ DC voltage gain of 85 dB, and a unity gain bandwidt~,~~F,> 1.0 MHz with 58 of phase margin (Figure 4&? .~~~;w noninverting input is internally biased at 2.5 V ~~&Y@*~d is not pinned out. The output voltage of the ~~t~~ctor converter is typically divided down and moti@{~@by the inverting input. The maximum input bias ,G@R~~~Js-1.0 ~ which can cause an output voltage er~; t~af is equal to the product of the input bias curre~B@-~$e value of the upper divider resistor R2. Th,R.e,&r& Amp Output is internally connected to the wt~p%r and is pinned out (Pin 2) for external loo~r.som~~nsation. Typically, the bandwidth is set beiow,i~{s~, so that the Error Amp output voltage is rela&g~~i, &nstant over a given AC line cycle. The output .~t~ev'~onsists of a 500 @ current source pull-up wi@,~$&:~~rlington transistor pull-down. It is `apable of sw~$'&n&&from 2.1 V to 5.7 V, assuring that the Multiplier ~~,%s~hven over its entire dynamic range: :,,,5~,, ,Multiplier%l{;' A si~@,.~uadrant: two input multiplier is the critical ~~t: .J ?fement }&at enables this device to control power factor. rhe AC haversines are monitored at Pin 3 with respect to ground while the Error Amp output at Pin 2 is monitored with respect [O the Voltage Feedback Input threshold. A graph of the Multiplier transfer curve is shown in Figure 1. Note that both inputs are extremely linear over a wide oynamic range, O V to 3.2 V for the Multiplier input (Pin 3), and 2.5 V to 4.0 V for the Error Amp output (Pin 2). The Multiplier output controls the Current Sense Comparator threshold (Pin 4) as the AC voltage traverses sinusoidally from zero to peak line. This has the effect of forcing the, MOSFET peak current to track the input line voltage, thy~~:<, making the preconverter load appear to be resistive. ~v"':~~,~p ~ .$+PS Pin 4 Threshold = 0.62(VHn z - VFB)VPi~J~J++lJ* ~,p'!f .i' ~.;i,:< `J. !>,.>,t.+,,:'~{:?+ ~ Zero Current Detector The MC34261 operates as a critical con,~'~t;w%urrent mode controller, whereby output swit~&$~~~@&uction is initiated by the Zero Current Detector am{e~~';nated when the peak inductor current reaches'$t~he"'t% reshold level established by the Multiplier o@&~f$tThe Zero Current Detector initiates the next on-~~~'m%etting the RS Latch at the instant the inductor cum~,@~g@&ches zero. This critical conduction mode of opera~w~s two significant benefits. First, since the MOSF,@~i cafimot turn on until the inductor current reaches zerb~k:&mput rectifier's reverse recovery time becomes lesS~rrt&?allowing the use of an inexpensive rectifier. Seco@~ 5&$~here are no deadtime gaps between cycles, the ,fi~-~e current is continuous thus limiting the peak swit@%$totwice the average input current. Th~l@~~ burrent Detector indirectly senses the inductor curt~pfl~~:~bonitofing when the auxiliay winding voltage falls b~$~~~.1~ V. To prevent fafse tripping, 110 mV of hysteresis is ~~vided. The Zero Current Detector input is internally p~otected by two clamps. The upper 6.7 V clamp prevents input overvoltage breakdown while the lower 0.7 V clamp prevents substrate injection. Device distribution can result if this input is shorted to ground. An external resistor must be used in series with the auxitia~ winding to limit the current through the clamps. ~"-\ ~, ! `\ (-") "L Current Sense Comparator and RS btch The Current Sense Comparator RS Latch configuration ensures that only a single pulse appears at the Drive Output during a given cycle. The inductor current is converted to a voltage by inserting a ground referenced sense resistor Rg in series with the source of output switch QI. Ttis voltage is monitored by the Current Sense Input and compared to the Multiplier output voltage. The peak inductor current is controlled by the threshold voltage of Pin 4 where: ipk= Pin 4 Threshold Rg With the component values shown in Figure 16, the Current Sense Comparator threshold, at the peak of the haversine varies from 1.1 V at 90 Vac to 100 mV at 268 Vat. The Current Sense Input to Drive Output propagation delay is typically 200 ns. .:. Q IOTOROLA MC34261 . MC33261 Timer F A. A watchdog timer function was added to the IC to eliminate the need for an external oscillator when used in stand alone applications. The Timer provides a means to automatically sta.rf or restart the preconvefier if the Drive output has been off for more than 400 ~S after the inductor current reaches zerc. condition. used This feature is desirable if external the start-up of the preconverter. output The MC34261 /MC33261 contain a single totem pole output stage specifically designed for direct drive of power MOSFETS. The Drive Output is capable of up to ~500 mA peak current with a typical rise and fall time of 50 ns with a 1.0 nF load. Additional internal circuitry has been added to keep the Drive Output in a sinking mode whenever the Undervoltage Lockout is active. This characteristic eliminates the need for an external gate pull-dcrk.n resistor. The totem pole output has been optimiZ$,@\$b$hinimize The cross conduction current during high spe~~ *@*tion. addition of two 10 Q resistors, one in $$'~$&h the source output transistor and one in seties~,@~'?he sink output transistor, reduces the cross coR&@i?W8urrent, as shown in Figure 12.

In the standby mode, with VCC at 7.0 V, the required supply current is less than 0.5 mA (Figure 13). This hysteresis and low start-up current allow the implementation of efficient bootstrap start-up techniques, making these devices ideally suited for wide input range off line preconverter applications. An internal 36 V clamp has been added from VCC to ground to protect the IC and capacitor C5 from an overvoltage ,~.:~.. .*J. ,, Calculation ~ ~.!.,,X, ., t,. `~i$:~ ~ $,~ig,k ,,:,$.` Formula Required Converter Output Power 2ti lL(pk) = maximumrequiredoutputpower. i$~+';~s?:,y ~%wtd at the minimum required AC fine for Po ~:~:e,~lation.
