Maximising Efficiency and Cutting Costs with Traco Power POL Regulators

Traco Power has launched two new series of non-isolated DC/DC switching converters, the TSR 2N and TSR 3N, designed to replace inefficient linear regulators.

Housed in a compact SIP-3 package, these POL switching regulators save valuable space on your PCB and simplify design for space-constrained applications. Their efficient design also leads to lower product prices, reduced material (BOM) costs, and more affordable manufacturing for end devices, while maintaining the trusted quality and reliability of Traco Power.

Key Features of Traco Power POL Switching Regulators: 

• High efficiency: With up to 96% efficiency, these regulators cut down on energy loss, remove the need for heat sinks, and can handle full load temperatures up to +67 °C. 
   
• Wide input range: The TSR 2N series works with input voltages from 4,6 to 36 VDC, while the TSR 3N covers 6,5 to 36 VDC, giving you flexibility for various power sources. 
   
• Precise output voltage: Both series offer precise output voltage control with a typical accuracy of ±2%, ensuring reliable performance for sensitive electronics.
    
• Compact design: The SIP-3 package is just 0.55” x 0.30” x 0.40” in size, making it easy to fit into existing devices without significant PCB changes. 
   
• Built-in features: Integrated filtering capacitors and short-circuit protection add extra reliability and simplify your design by reducing the need for external components. 
   
• Pre-set output voltages: Choose from models with output voltages of 1,2; 1,5; 1,8; 2,5; 3,5; 5,0; 6,5; 9; 12; 15 VDC. 
   
• Cost-effective solution: Lower BOM costs while maintaining quality in industrial device design.

Traco Power POL switching regulators are perfect for a variety of applications, including:  

• Battery-powered devices
• Industrial control systems
• Embedded systems
• Telecommunications equipment

„Switching from traditional linear regulators to the TSR 2N or TSR 3N series helps improve efficiency, cut down on cooling needs, and keep things compact. This means you get more reliable, energy-efficient products, with lower production costs and a more competitive final price, “ explained Pavel Kováč, Product Manager at SOS Electronic.

The features of Traco Power’s new generation of non-isolated POL switching regulators in the TSR N series simplify the manufacturing process (DFM – Design for Manufacturability) by minimizing production risks, optimizing manufacturing costs, and accelerating time-to-market. This makes entire projects faster and more cost-effective.
