Overview
The SG2524BDW is a high-reliability isolated switching regulator manufactured by Microchip Technology. It operates in voltage mode with pulse width modulation control, supporting topologies including boost, buck, flyback, forward, and push-pull. The device features a maximum switching frequency of 600 kHz and a maximum duty cycle of 45%. It accepts an input voltage range from 7 V to 40 V, with a nominal input of 19 V. The output current capability is 50 mA, and the reference voltage tolerance is +/-1%. It functions within a temperature range of -25°C to +85°C and is housed in a 16-SOIC package.
Feature Summary
- Supports multiple power converter topologies including flyback, forward, and push-pull configurations
- Provides high-reliability isolated switching regulation capabilities
- Features voltage-mode control with adjustable pulse width modulation
Applications
- Isolated DC-DC power supply designs
- Industrial power management systems
- High-reliability electronic equipment power stages
Procurement Notes
Verify the manufacturer designation carefully, as the SG2524 series has been produced by multiple vendors including Texas Instruments and Linfinity. Confirm that the specific part number SG2524BDW corresponds to the Microchip Technology variant rather than other manufacturers' equivalents. Ensure the 16-SOIC package type matches the design requirements. Check for any specific reliability certifications required for the intended application environment.
Selection Notes
Select this component when a high-reliability isolated switching controller is required for complex power topologies. The voltage-mode control suits applications needing precise regulation across various converter types. Consider the 7 V to 40 V input range for compatibility with standard bus voltages. The 16-SOIC package facilitates surface-mount assembly. Evaluate the 600 kHz maximum frequency against thermal and efficiency constraints of the target design.
Part Context
The SG2524BDW belongs to the SG2524 series of switching controllers, known for their robust performance in isolated power applications. This specific variant is manufactured by Microchip Technology and utilizes a 16-SOIC surface-mount package. It serves as a core control element in power supplies requiring high reliability and support for diverse converter architectures such as flyback and push-pull.
Replacement Considerations
Cross-reference with SG2524BN or SG2524DR if pin-compatible alternatives are needed, though manufacturer-specific characteristics may vary. Verify electrical parameters and package dimensions before substitution.
