- DN-28 UC3840/UC3841/UC3851 PWM Controllers - Summary of Functions & DifferencesPDF, 22 Kb, Datei veröffentlicht: Sep 5, 1999
The UC3840/UC3841 and UC3851 PWM controllers incorporate numerous protection features for switch mode power supplies. The list includes programmable undervoltage lockout thresholds, programmable current-limit thresholds, overvoltage protection, soft-start, and external stop/reset capability. While these controllers are similar in concept, there are subtle differences among them in the operation of
