Introducing a bidirectional buck-boost voltage regulator, the ISL95338, that 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 transitions between discontinuous and continuous conduction modes. The ISL95338 takes input power from a wide range of DC power sources (conventional AC/DC adapters, USB-PD ports, and travel adapters) and safely converts it to a regulated voltage up to 24V. The ISL95338 can also convert a wide range of DC power sources connected at its output (system side) to a regulated voltage to its input (ADP side). This bidirectional buck-boost regulation feature makes its applications very flexible. The ISL95338 includes various system operation functions such as forward mode enable, reverse mode enable, programmable soft-start time, and adjustable output voltage 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. The ISL95338 is available in a 32-lead, 4mm x 4mm TQFN package. This is an ideal solution for any customer looking to implement USB power delivery in any end devices with USB Type-C ports.
