Overview
The SG2524BJ is a high-reliability isolated switching regulator manufactured by Microchip Technology. It operates as a flyback regulator with positive output step-up/step-down capabilities. The device utilizes voltage-mode PWM control and supports switching frequencies up to 600kHz. It features a maximum output current of 100mA and functions within an input voltage range of 19V. Packaged in a 16-pin Ceramic Dual In-Line Package (CDIP), it is designed for robust industrial applications requiring stable DC-DC conversion.
Feature Summary
- High-reliability isolated switching regulator design
- Voltage-mode pulse width modulation control
- Flyback topology with step-up/step-down capability
Applications
- Industrial power supply systems
- Isolated DC-DC conversion modules
- High-reliability electronic equipment
Procurement Notes
Verify the specific manufacturer designation, as the SG2524 series originated from Texas Instruments and was later acquired by Microchip Technology. Confirm that the CDIP package matches the required isolation and thermal specifications for the target application. Ensure compliance with any legacy component sourcing requirements if replacing older designs.
Selection Notes
Select this component when high reliability and isolation are critical for the power management system. The voltage-mode control suits applications where simple loop compensation is preferred. Consider the 100mA output limit and 600kHz frequency against the specific power and size constraints of the design.
Part Context
The SG2524BJ belongs to the SG2524 family of switching controllers, which were originally developed by Texas Instruments before being transferred to Microchip Technology. This series is known for its use in offline and isolated power supplies. The BJ suffix typically denotes the ceramic dual in-line package variant optimized for durability.
Replacement Considerations
Direct replacements may include other variants within the SG2524 family such as the SG2524D or SG2524BN, though package differences exist. Verify pin compatibility and electrical parameters before substitution.
