Rev.1.00
Oct 5, 2017 Bidirectional Buck-Boost Voltage Regulator The ISL95338 is a bidirectional, buck-boost voltage
regulator that provides buck-boost voltage regulation and
protection features. Intersil’s advanced R3™ Technology
is used to provide high light-load efficiency, fast transient
response, and seamless DCM/CCM transitions. Features Bidirectional buck, boost, and buck-boost operation Input voltage range 3.8V to 24V (no dead zone) Output voltage up to 20V The ISL95338 takes input power from a wide range of
DC power sources (conventional AC/DC ADPs, USB PD
ports, travel ADPs, etc.) and safely converts it to a
regulated voltage up to 24V. The ISL95338 can also
convert a wide range DC power source connected at its
output (system side) to a regulated voltage to its input
(ADP side). This bidirectional buck-boost regulation
feature makes its application very flexible. Up to 1MHz switching frequency The ISL95338 includes various system operation
functions such as Forward mode enable, Reverse mode
enable, programmable soft-start time, and adjustable
VOUT in both the forward direction and reverse direction.
The protection functionalities include OCP, OVP, UVP,
OTP, etc. Bypass mode in both directions The ISL95338 has serial communication through
SMBus/I2C that allows programming of many critical
parameters to deliver a customized solution. These
programming parameters include, but are not limited to: …
