ISL95338EVAL1Z

Bidirectional Buck-Boost Voltage Regulator Evaluation Board

Description

The ISL95338EVAL1Z board evaluates the ISL95338 bidirectional buck-boost voltage regulator, which provides bidirectional buck-boost voltage regulation and protection features. Intersil's advanced R3TM 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 has 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.
