ISL95338 Bidirectional Buck-Boost Voltage Regulator

Renesas' ISL95338 is a bidirectional, buck-boost voltage regulator, which provides buck-boost voltage regulation and protection features. Renesas' advanced R3™ technology is used to provide high light-load efficiency, fast transient response, and seamless DCM/CCM transitions.

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 24 V. 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.

The ISL95338 includes various system operation functionalities such as Forward mode enable, Reverse mode enable, programmable soft-start time, adjustable V_OUT, in both forward and reverse directions. The protection functionalities include OCP, OVP, UVP, and OTP.

The ISL95338 has serial communication via SMBus/I²C which allows programming of many critical parameters to deliver a customized solution. These programming parameters include, but are not limited to: output current limit, input current limit, and output voltage setting.
