STW4410 数据手册 ( 数据表 ) - STMicroelectronics

Description
STw4410 is a power management device with advanced features. The two Switched Mode Power Supplies (SMPS) and the four Low Drop Output regulators (LDO) had been designed to use the better external components, to have the better efficiency and the better noise rejection to the load and line transient perturbation.
This product suits well all mobile applications thanks to its very low consumption in sleep mode.
