Od autorów Oddajemy do r¹k Czytelników drug¹ czêœæ publikacji Uk³ady steruj¹ce w zasilaczach i przetwornicach, w której kontynuujemy przegl¹d praktycznych zastosowañ uk³adów scalonych w zasilaczach i przetwornicach. Podobnie jak w pierwszej czêœci, tak i w tej, zebrane zosta³y aplikacje, a w niektórych przypadkach równie dane katalogowe uk³adów, które stosowane s¹ w zasilaczach i przetwornicach. Nie ograniczaliœmy siê tylko do przetwornic sieciowych, wystêpuj¹cych w odbiornikach telewizyjnych, monitorach, magnetowidach, czy te w sprzêcie audio. Sporo miejsca poœwiêciliœmy uk³adom pracuj¹cym w niskonapiêciowych przetwornicach DCDC, które coraz czêœciej pojawiaj¹ siê na rynku, na przyk³ad w najró niejszych ³adowarkach, a tak e sprzêcie montowanym w samochodach. Wœród uk³adów steruj¹cych prac¹ przetwornic impulsowych zasilanych napiêciem sieciowym daje siê zauwa yæ tendencjê do integracji wysokonapiêciowego tranzystora kluczuj¹cego i rozbudowanego uk³adu steruj¹cego w strukturze jednego uk³adu scalonego. Doskona³ym przyk³adem takiego rozwi¹zania s¹ uk³ady z serii MIP firmy Panasonic, w których ca³oœæ uk³ad steruj¹cy i klucz uda³o siê wcisn¹æ w trójkoñcówkow¹ obudowê TO0. Podobnie jest z uk³adami firmy Fairchild, które z regu³y upakowane s¹ w piêciokoñcówkowej obudowie TO0, np. seria KAQ, KAS Oprócz tych nowinek wœród podzespo³ów znajdziecie Pañstwo swoich starych znajomych z popularnych serii STR i STK Prezentowana ksi¹ ka nie aspiruje do rangi katalogu, mimo zamieszczenia dla czêœci uk³adów podstawowych parametrów elektrycznych. Nie jest ona zatem adresowana do projektanta, czy te konstruktora sprzêtu. Przy doborze materia³ów g³ówny nacisk po³o ono na stronê praktyczn¹, a wiêc: schemat blokowy, aplikacjê zalecan¹ przez producenta i co najwa niejsze praktyczne zastosowanie, czyli fragment schematu urz¹dzenia, w którym dany uk³ad scalony zosta³ zastosowany. Liczne opinie jakie otrzymaliœmy od Czytelników zajmuj¹cych siê serwisowaniem elektronicznego sprzêtu powszechnego u ytku po wydaniu pierwszego tomu Uk³adów steruj¹cych potwierdzi³y przyjêt¹ przez nas formu³ê tej ksi¹ ki. W sytuacji, gdy na warsztat trafia urz¹dzenie, do którego brak schematu, przyk³adowa aplikacja uk³adu pozwala na zdiagnozowanie uszkodzenia zasilacza i niejednokrotnie stanowi nieocenion¹ pomoc w naprawie. W czêœci Uk³adów steruj¹cych w zasilaczach i przetwornicach zamieœciliœmy informacje dotycz¹ce 0 uk³adów, w tomie jest ich. W celu szybkiego wyszukania ¹danego uk³adu, wzorem naszych poprzednich publikacji zamieœciliœmy spis treœci obu tomów, przy czym uk³ady wystêpuj¹ce w czêœci drugiej zosta³y wyt³uszczone. Licz¹c na przychylne przyjêcie prezentowanej publikacji podajemy nasz adres internetowy: redakcja@serwiselektroniki.com.pl, na który prosimy przesy³aæ wszelkie uwagi dotycz¹ce zarówno tomów ju wydanych, jak równie propozycji uk³adów, które powinny znaleÿæ siê w kolejnej czêœci Uk³adów steruj¹cych.

AN0, AN0S Opis wyprowadzeñ uk³adów AN0 i AN0S Pin No. Symbol Description TR Transformer reset. When a transformer reset is detected, i.e., a low level is input to this pin, the IC output goes high. However, the transformer reset signal is ignored during the minimum offperiod determined by the CF pin. The maximum onperiod is also corrected according to the current flowing out of this pin. RSTB Adjusts the lightload detection level that determines the when the IC switches from RCC to discontinuous operation. When the voltage (V FB ) which is IV conversion of current feedback signal from IFB pin goes up higher than this pin, minimum offperiod current at CF pin decreases, and operating frequency decreases. The detection level can be adjusted arbitrarily using an external pulldown resistor. CF Connection for the capacitor that determines the on and off periods for the IC output (Out). IFB Input for the current feedback signal from the power supply output photocoupler CLM Input of the pulsebypulse overcurrent protection circuit. Normally, it will be necessary to add an external filter for this input. Ground. V OUT Output to drive a power MOSFET directly. Vcc Power supply. This pin watches Vcc and has operating threshold voltages for the start, stop, OVP and OVP reset levels. Schemat aplikacyjny E IN V OUT CC PC ANMS RSTB IFB AN0 AN0S Out PC TR CLM CF EIN
