Datasheet for the SG2524, a 107 KB PDF covering a member of the long-established 2524/3524 family of regulating pulse-width modulators. No revision or manufacturer is given in the name. Engineers and technicians use it to identify the reference output, error amplifier inputs, oscillator pins, current-limit sense and output transistors when repairing older switch-mode supplies. Note that 2524 versions are rated for a different temperature range than 3524 types, so check the grade when substituting.
