Overview
The SG2524D is a regulating pulse-width modulator manufactured by Texas Instruments, designed for switch-mode power supply applications. It supports multiple topologies including boost, buck, flyback, forward, and push-pull configurations. The device features two output channels with a maximum switching frequency of 450 kHz and a maximum duty cycle of 45%. It operates within an ambient temperature range of -25°C to +85°C and is housed in a 16-pin SOIC-Narrow package.
Feature Summary
- Supports versatile converter topologies such as boost, buck, flyback, forward, and push-pull
- Provides dual output channels for synchronized control applications
- Includes integrated shutdown functionality for system power management
Applications
- DC-DC converter designs utilizing boost or buck architectures
- Flyback power supply implementations
- Forward converter systems requiring regulated pulse width modulation
Procurement Notes
Verify the specific manufacturer source, as the SG2524 part number is historically associated with Microsemi and other vendors. Confirm that the Texas Instruments variant matches the required electrical specifications and pinout compatibility for your design. Ensure the component meets RoHS compliance requirements if mandated by your project standards before finalizing procurement.
Selection Notes
Select this component when a dual-output PWM controller supporting multiple power topologies is required. Consider the 450 kHz switching frequency limit and 45% duty cycle constraint during circuit design. Verify thermal performance within the specified -25°C to +85°C operating range for your intended environment.
Part Context
The SG2524 series belongs to the family of regulating pulse-width modulators used in power management ICs. While originally developed by National Semiconductor and later acquired by Texas Instruments, similar parts are also produced by other manufacturers like Microsemi. This specific model serves as a core control element in various industrial and commercial power conversion systems.
Replacement Considerations
Public confirmed substitute part numbers include SG3524DR and SG3524DRE4 from Texas Instruments. These alternatives share similar functional characteristics but may differ in temperature ranges or specific electrical parameters.
