SG3524N Description

On a single chip, the SG2524 and SG3524 devices include all of the functionalities needed to build a regulating power supply, inverter, or switching regulator. They can also be utilized as a control element in applications with high power output. The SG2524 and SG3524 were created for fixed frequency, pulse-width modulation (PWM) polarity-converter applications, transformer-coupled dc to dc converters, transformerless voltage doublers, and polarity-converter applications. The complementary output can be used as a single-ended or push-pull signal. On-chip regulators, error amplifiers, programmable oscillators, pulse-steering flip-flops, two uncommitted pass transistors, a high-gain comparator, and current limiting and shutdown circuitry are all included in each device.
