Why EMI and Noise Control Matter

Electromagnetic interference (EMI) is a major challenge in modern power systems. In safety-critical applications such as vehicles, medical equipment, and industrial controllers, noise can disrupt signals, reduce reliability, or even compromise safety.

The TPSM33615 addresses this problem with:

• Integrated EMI filters: Reducing the need for external filtering components
• Spread spectrum modulation: Distributing noise over a wider frequency band, lowering peak interference
• Cleaner signals: Ensuring reliable operation of sensitive circuits

This combination allows designers to meet strict compliance standards without adding design complexity.

Applications of TPSM33615

Automotive Systems:Cars demand reliable power across a wide range of operating conditions. From infotainment to advanced driver assistance systems (ADAS), the TPSM33615 provides stable voltage while controlling EMI that could affect sensitive electronics.

Industrial Equipment:Industrial automation, motor drives, and robotics require power solutions that work reliably in electrically noisy environments. With its wide input range and EMI suppression, the TPSM33615 fits these use cases perfectly.

Safety-Critical Electronics:Medical equipment, communication systems, and aerospace electronics all rely on uninterrupted power. The TPSM33615 delivers clean and dependable output, supporting critical functions where safety comes first.

Benefits for Engineers and System Designers
