Step-up/Step-down (Buck-Boost)

A buck-boost converter generates an output voltage either greater or less than the input voltage. The advantage of using a buck-boost solution is regulating the output voltage over the full power source voltage range. Buck-boost converter solutions usually have lower efficiency and a larger footprint than buck converter solutions.

The ISL9120 offers designers the flexibility to cover a variety of design needs by operating from a Vin of 1.8V to 5.5V and an adjustable output voltage from 1V to 5.2V. Its adaptive PFM operation with forced bypass mode and 2A switches support both low load and high load currents with high efficiency, ensuring longer battery life and less heat buildup. The regulator also delivers 800mA current with 2.5V input and 3.3V output.

Renesas Electronics Corporation today introduced the industry’s first USB-C™ buck-boost battery charger to support both Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck-Boost (HPBB) charging for notebooks, ultrabooks, tablets, and power banks using the reversible USB Type-C™ connector cable. Through firmware control, the ISL9241 can switch between NVDC and HPBB modes, providing a low-cost and small solution size capable of efficiently processing a full range of power levels.
