Intersil announced the industry's first buck-boost voltage regulator for tablets, ultrabooks, power banks, and other mobile devices using the reversible USB Type-C™ connector. The ISL95338 bidirectional voltage regulator accepts input power from a wide range of DC power sources - AC/DC power adapters, USB power delivery (PD3.0) ports, travel adapters, power banks - and converts it to a regulated voltage up to 24V. The ISL95338 can also convert a wide range of DC power sources to a regulated 20V at its power adapter input. The ISL95338 supports the USB-C ecosystem with buck-mode, boost-mode, and buck-boost mode, and is flexible enough to use in any USB-C power management application.

The single-chip ISL95338 replaces two voltage converters currently used for bidirectional buck and boost modes to reduce a customer's bill of materials (BOM) cost by 50%. It leverages Intersil's patented R3™ modulation technology to deliver acoustic noise-free operation, superior light-load efficiency and ultra-fast transient response. Intersil's R3 extends battery life by combining the best features of fixed-frequency pulse width modulation (PWM) and hysteretic PWM to maximize power efficiency. The ISL95338 is also USB 3.1-compliant and provides serial communication through SMBus/I2C, allowing designers to program several input/output current and voltage slew rate settings to create a customized solution.
