SG3525 Controlador PWM PWM para Fuentes conmutadas, control de motores Encapsulado Smd SO16 y Dip16 Descargar PDF SG3525 DC/DC Converter 12V to +35V,-35V Switch mode Power Supply For Car Audio The selected switching topology is called a “push-pull” converter, because the transformer has a double primary (or a “centre-tapped” one, if your prefer). This control circuit is ideal for the accurate control of DC motors as well as other applications like lighting levels and small heaters etc. The circuit converts a DC voltage into series of pulses, such that the pulse duration is directly proportion to the value of the DC voltage.
