3 Description
The TPS562201 and TPS562208 are simple, easy-touse, 2-A synchronous step-down converters in SOT-23 package.
The devices are optimized to operate with minimum external component 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 capacito...
