Texas Instruments (TI) today launched a new stackable integrated circuit (IC) 40-A SWIFT™ DC/DC buck converter. The TPS546D24A PMBus buck converter can deliver up to 160A of output current at an ambient temperature of 85°C, which is four times higher than other power integrated circuits on the market. Among many 40A DC/DC converters, the TPS546D24A … Read more
Hard Switch Circuit Design Example The hard switch circuit converts the series voltage of two 7-cell batteries into a 3.3 V voltage through the DC/DC converter MAX756, as shown in Figure 1. If powered directly by the batteries without a boost circuit, the voltage at the battery terminal will experience a decline from high to … Read more
When automotive applications can accomplish more work with fewer parts, it can enhance reliability while reducing weight and costs. This is the idea of integrating electric vehicle (EV) and hybrid electric vehicle (HEV) designs with an all-in-one powertrain system. What is an All-in-One Powertrain Architecture? The all-in-one powertrain architecture integrates terminal devices such as onboard … Read more

In 1950, the widespread use of high-displacement engines in automobiles made the existing 6V voltage system inadequate to meet the growing electrical demands. Automotive companies adopted a method of connecting two 6V batteries in series to create a 12V low-voltage system. By the late 1960s, nearly all vehicles had adopted the 12V voltage system, with … Read more
