TPS562219 Overview
The TPS562219 and TPS563219 are simple, easy-touse, 2-A, 3 -A synchronous step-down converters in 8 pin SOT-23 package. The devices are optimized to operate with minimum external ponent counts and also optimized to achieve low standby current. These switch mode power supply (SMPS) devices employ D-CAP2™ mode control providing a fast transient response and supporting both low equivalent series resistance (ESR) output...
