The ISL95338 is a bidirectional, buck-boost voltage regulator that provides buck-boost voltage regulation and protection features. The Renesas advanced R3™ Technology provides 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 (such as conventional AC/DC ADPs, USB PD ports, and travel ADPs) and safely converts it to a regulated voltage up to 20V. 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 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, and OTP. 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: output current limit, input current limit, and output voltage setting.
