SG3524N

Overview

The SG3524N is a voltage-mode PWM controller from Texas Instruments, housed in a 16-pin PDIP package for through-hole mounting. It operates within an input supply range of 8V to 40V and supports switching frequencies up to 450 kHz. The device features dual outputs with a maximum duty cycle of 45% and provides an output current capability of 100mA. Designed for industrial applications, it functions reliably across a temperature range of 0°C to 70°C.

Feature Summary

Integrates complete PWM power control circuitry including error amplifier, programmable oscillator, and pulse-steering flip-flop on a single monolithic chip.
Provides uncommitted dual outputs suitable for both single-ended and push-pull converter topologies.
Includes dedicated current-limiting and shutdown circuitry for enhanced protection and operational safety.

Applications

Transformer-coupled DC-to-DC converters
Switching regulators and inverters
Voltage doublers and polarity converters

Procurement Notes

Verify the specific manufacturer source, as STMicroelectronics also produces the SG3524N variant. Confirm that the component matches the Texas Instruments specification sheet regarding the 450 kHz frequency limit and 100mA output drive capability. Ensure the PDIP-16 package aligns with the required through-hole assembly process.

Selection Notes

Select this component for designs requiring robust voltage-mode control with integrated protection features. It is appropriate for applications needing dual-output flexibility for push-pull or single-ended configurations. Consider the 450 kHz maximum frequency when designing external timing components and ensuring thermal management within the specified operating temperature range.

Part Context

This part belongs to the SG series of regulating pulse width modulators. It serves as a foundational control IC for various power supply architectures. The device consolidates essential control functions into one unit, reducing external component count compared to discrete solutions.
