Rev.1.00
Oct 4, 2017 Buck-Boost Narrow VDC Battery Charger for Power Bank Application with
SMBus Interface and USB OTG
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. Intersil’s advanced R3™ Technology is used
to provide high light-load efficiency and fast transient
response.
In Charging mode, the ISL95538B takes input power
from a wide range of DC power sources (conventional
AC/DC charger adapters, USB PD ports, travel adapters,
etc.) and safely charges battery packs with up to 4-series
cell Li-ion batteries. Features Buck-boost NVDC charger for 1-, 2-, 3-, or 4-cell
Li-ion batteries Input voltage range 3.2V to 23.4V (no dead zone) System output voltage 3V to 18.304V Autonomous charging option (automatic end of
charge and recharge) Up to 1MHz switching frequency Adapter current and battery current monitor
(AMON/BMON) As an NVDC topology charger, it 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 …
