説明

The ISL95538B is a buck-boost Narrow Output Voltage DC (NVDC) charger. The ISL95538B provides the NVDC charging function, system bus regulation, and protection features for tablet, Ultrabook, and notebook platforms. The advanced Renesas R3™ Technology provides high light-load efficiency and fast transient response. In Charging mode, the ISL95538B takes input power from a wide range of DC power sources (such as conventional AC/DC charger adapters, USB PD ports, travel adapters) and safely charges battery packs with up to 4-series cell Li-ion batteries. As an NVDC topology charger, the ISL95538B also regulates the system output to a narrow DC range for stable system bus voltage. The system power can be provided from the adapter, battery, or a combination of both. The ISL95538B can operate with only a battery, an adapter, or both connected. The ISL95538B supports reverse buck, boost, or buck-boost operation to the input port from 2- to 4-cell batteries. The ISL95538B has serial communication using SMBus/I2C that allows programming of many critical parameters to deliver a customized solution.
