SG3524 Description

Short technical summary and product information.

The SG3524 is a versatile integrated circuit that incorporates complete pulse-width modulation (PWM) power-control circuitry on a single chip. It is designed for use in regulating power supplies, inverters, and switching regulators of any polarity. The device includes an on-chip regulator, error amplifier, programmable oscillator, and complementary outputs suitable for single-ended or push-pull applications.

 

Key electrical specifications include a wide supply voltage range of 8V to 40V, an output voltage range of 4.6V to 5.4V, and a maximum output current of 50mA. The switching frequency can reach up to 722 kHz with a maximum duty cycle of 45%. The SG3524 is available in multiple package types, including 16-pin SOIC, PDIP, and NS, with various body sizes to accommodate different design requirements.

 

This IC is well-suited for applications such as transformer-coupled DC/DC converters, transformerless voltage doublers, and polarity converters. Its integrated functions simplify the design of high-power-output applications, making it a valuable component for power management solutions.
