SG3525 Overview
The SG3525Aseries of pulse width modulator integrated circuits are designed to offer improved performance and lowered external parts count when used in designing all types of switching power supplies. The on-chip + 5.1 V reference is trimmed to ± 1 % and the input mon-mode range of the error amplifier includes the reference voltage eliminating external resistors. A sync input to the oscillator allows multiple units...
