eGaN FETs target USB-C chargers, PoL conveters
Efficient Power Conversion Corporation advances the performance capability of low voltage, off-the-shelf gallium nitride transistors with the introduction of the EPC2055 (3 mΩ, 40 V) eGaN FET. This device is ideal for applications with demanding requirements for performance in space-constrained form factors including USB-C battery chargers and ultra-thin point-of-load (POL) converters. Other low-voltage applications benefiting from […]
Understanding stop/start automobile-engine design, Part 3: The battery situation
The stop/start approach has significant implications for the car’s battery and battery management system (BMS). Q: How does the battery charge/discharge cycle function in a non-stop/start vehicle? A: In a car without a stop/start system, starting the engine is a one-time event for the duration of the trip. While the engine is running, it also […]
Understanding stop/start automobile-engine design, Part 1: The idea
Today’s motor vehicles are vastly different compared to those of just a decade ago. This article will look at a relatively new “feature” (some say an unneeded and unwanted one) called “stop/start” which is increasingly standard on many internal combustion and hybrid electric vehicles (HEVs). Q: What is stop/start? A: It’s a simple idea, at […]
