Overview
The SG3524BDW-TR is a switching voltage regulator controller from Microchip Technology, designed for high-reliability isolated applications. It operates within an input voltage range of 7 V to 40 V and supports switching frequencies between 400 kHz and 600 kHz. The device features a temperature range of 0°C to 70°C and utilizes a 16-pin SOIC package with tape and reel packing media containing 1000 units.
Feature Summary
- Supports high-reliability isolated switching regulator topologies
- Operates at switching frequencies up to 600 kHz
- Includes +/-1% reference accuracy specification
Applications
- Isolated switching regulators
- Voltage mode PWM control circuits
- High-reliability power supply designs
Procurement Notes
Verify the specific manufacturer part number against the datasheet to ensure compatibility with the required switching frequency range of 400 kHz to 600 kHz. Confirm that the 16-pin SOIC package and tape and reel packaging meet the assembly requirements. Cross-reference the operating temperature range of 0°C to 70°C with the environmental conditions of the target application to ensure reliable performance.
Selection Notes
Select this component when designing isolated switching regulators requiring precise voltage mode control. The wide input voltage range of 7 V to 40 V provides flexibility for various power stages. Ensure the design accommodates the specified switching frequency limits and thermal constraints. The integrated reference accuracy aids in maintaining stable output voltages without external calibration components.
Part Context
This model belongs to the SG3524 family of PWM controllers, which are widely used in regulating power supplies and inverters. The BDW suffix indicates a specific industrial-grade variant packaged in a 16-pin SOIC format. The -TR designation confirms the tape and reel delivery method, suitable for automated surface-mount assembly processes.
Replacement Considerations
Direct substitutes include other SG3524 variants such as the SG3524N or SG3524DR, provided they match the pinout and electrical specifications. Verify that alternative packages support the same thermal and frequency requirements for seamless integration.
