The SG3524D is a voltage-mode, pulse-width modulator control integrated circuit (IC) produced by Texas Instruments. It contains all of the necessary control components for the construction of a voltage-mode, pulse-width modulated (PWM) switching power supply in a single package. It includes an error amplifier, an adjustable oscillator, two drivers for high- or low-side power switches, two amplify-and-control stages and three fixed voltage reference (REF) terminals. The SG3524D is commonly used in DC/DC converters, AC line-operated power supplies, and current-mode switching power supplies. The output of the IC can be adjusted in voltage, current, and power levels.
