SG2524D

Overview

The SG2524D is a high-performance switching regulator integrated circuit manufactured by Microchip Technology. It operates within a supply voltage range of 7.5V to 35V and features an adjustable frequency control via an external resistor or capacitor. The device includes comprehensive protection mechanisms such as under-voltage lockout, soft-start capability, and over-current limiting. Designed for dual in-line package (DIP) configurations, it supports both single-ended and push-pull output topologies, making it suitable for various power conversion applications requiring stable regulation.

Feature Summary

• Integrated soft-start function to limit inrush current during startup
• Built-in under-voltage lockout for reliable operation at low input voltages
• Adjustable frequency control allowing customization of switching speed
• Over-current protection with latching or auto-restart options

Applications

• DC-DC converter designs
• Power supply units for industrial equipment
• Battery charging systems
• Telecommunications power modules

Procurement Notes

Verify the exact part number against official Microchip documentation to ensure compatibility with your design requirements. Confirm package type and temperature rating before procurement. Cross-reference datasheet specifications with your system's electrical needs to avoid mismatches. Ensure that ordering suffixes match intended functionality if applicable.

Selection Notes

Choose the SG2524D when precise voltage regulation and robust protection features are required. Its adjustable frequency allows optimization for efficiency and size constraints. Consider thermal management solutions based on expected load conditions. Evaluate whether its pinout aligns with existing PCB layouts to minimize redesign efforts.
