STMicroelectronics SG3524

The SG3524 incorporates on a single monolithic chip all the function required for the construction of regulating power suppies inverters or switching regulators. They can also be used as the control element for high power-output applications. The SG3524 family was designed for switching regulators of either polarity, transformer-coupled dcto-dc converters, transformerless voltage doublers and polarity converter applications employing fixed-frequency, pulse-width modulation techniques.
