Overview
The SG2526BDW-TR is a high-reliability isolated switching regulator manufactured by Microchip Technology. It operates as a voltage-mode PWM controller with a maximum switching frequency of 500 kHz. The device supports Buck, Flyback, and Forward topologies and features two outputs. It functions within an input voltage range of 8 V to 35 V, drawing 18 mA of operating current. The unit provides a regulated output voltage of 5 V at 100 mA. It includes shutdown functionality and exhibits rise and fall times of 300 ns and 100 ns, respectively. The component is housed in an SOIC-16 package for surface mount installation.
Feature Summary
- Voltage-mode pulse width modulation control for precise regulation
- High-reliability design suitable for isolated switching applications
- Integrated shutdown capability for power management
Applications
- Buck converter circuits
- Flyback power supply designs
- Forward topology converters
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm tape-and-reel packaging versus tube variants. Confirm RoHS compliance status through the manufacturer's current certification records. Ensure the ordering part number matches the required temperature grade and package style for your specific assembly process.
Selection Notes
Select this component for applications requiring high-reliability isolated switching regulation. Consider the 500 kHz switching frequency limit when designing magnetic components. Verify that the 8 V to 35 V input range aligns with your system's power supply architecture. Check compatibility with SOIC-16 footprint requirements during PCB layout.
Part Context
This part belongs to the SG2526B series of regulating pulse width modulators. It is categorized under PMIC - Power Management ICs and Switching Controllers. The device is designed for industrial and commercial environments requiring robust performance in voltage conversion tasks.
Replacement Considerations
Consult Microchip datasheets for direct pin-compatible alternatives within the SG2526 family. Verify electrical parameters such as switching frequency and output current capabilities before substitution.
