The ISL95338EVAL1Z evaluation board is used to evaluate the ISL95338 bidirectional buck-boost voltage regulator, which provides bidirectional 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 24V. The ISL95338 also can 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, and adjustable VOUT, in both forward direction and reverse direction. The protection functionalities include OCP, OVP, UVP, OTP, etc.

The ISL95338 offers serial communication using 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.
