When designing USB Type-C products, chargers, or power delivery systems, you face an increasingly complex challenge: verifying that your devices actually deliver what they promise . The USB Power Delivery specification has evolved rapidly with Extended Power Range (EPR) supporting up to 240W at 48V, multiple voltage profiles, and advanced protocols like Adjustable Voltage Supply (AVS) and Programmable Power Supply (PPS). But here's the real problem: Most engineers rely on b
