SG3525 LM358 Inverter Driver Board Mixer Preamp high Frequency Adjustable 12V-24V


The SG3525A pulse width modulator control circuit offers improved performance and lower external parts count when implemented for controlling all types of switching power supplies. The on-chip +5.1 V reference is trimmed to +-1% and the error amplifier has an input common-mode voltage range that includes the reference voltage, thus eliminating the need for external divider resistors. The output stage of the SG3525A features NOR logic resulting in a low output for an off-state.
