EVALTSM1052: Ultra small battery charger using TSM1052
Introduction
This document describes a low power adapter that can be used in travel battery charger
applications. It uses the new Constant Voltage Constant Current (CVCC) controller
TSM1052, which is housed in one of the smallest packages available (SOT23-6L). Thanks
to its low consumption and low operating voltage, good electrical performance is achieved.
Another important feature of this SMPS is the absence of the Y1 safety capacitor between
primary and secondary grounds.
