One key application is industrial handheld devices. These rugged units are feature-rich, somewhat space constrained with cooling issues and have multiple battery packs with high capacity. Therefore, IC input voltages tend to be >5V and typically 12V to 18V. They demand very power efficient, low heat generating regulators with multiple lower voltage higher current power rails. The 20V 12A LTC3376 PMIC meets these stringent demands.
