Overview
The SG2524BN is a pulse width modulator designed for switching power supplies, offering improved performance over industry standards. It operates in voltage-mode control with PWM technology. The device supports a maximum switching frequency of 400 kHz and delivers an output current of 0.2 A. Input voltage ranges from 7 V to 40 V, with a nominal value of 20 V. It functions within a temperature range of -25 °C to 85 °C. The component is housed in a 16-pin plastic DIP package.
Feature Summary
- Voltage-mode pulse width modulation control for switching power supplies
- Integrated shutdown capability for system management
- High-reliability isolated switching regulator design
Applications
- Flyback converter regulation
- Isolated switching power supply designs
- General-purpose DC-DC conversion systems
Procurement Notes
Verify the manufacturer source carefully, as the SG2524BN has been associated with multiple vendors including Linfinity Microelectronics and Microchip Technology. Confirm whether the specific unit is new or obsolete stock, as some listings indicate it is no longer manufactured by certain providers. Ensure the datasheet matches the required pinout and electrical specifications for your circuit design before finalizing procurement.
Selection Notes
Select this component for applications requiring robust voltage-mode PWM control with high reliability. It is suitable for designs needing a wide input voltage range up to 40 V. Consider the PDIP-16 package constraints for PCB layout. Verify compatibility with flyback topologies if isolation is required. Check thermal limits against the operating environment to ensure performance within the specified temperature range.
Part Context
The SG2524BN belongs to the SG2524 series of switching controllers. This family includes variants like the SG2524DR, which offers different packaging and slightly varied electrical characteristics such as a 450 kHz switching frequency. The SG2524BN specifically represents the bipolar, through-hole version often cited in legacy or high-reliability contexts.
Replacement Considerations
Public confirmed substitute part numbers are not explicitly listed in the provided documentation. Some sources mention available substitutes generally but do not name specific replacement models for the SG2524BN.
