DC-DC Buck-Boost Converters

Wide-Voltage Range With I2C-Configurable Output and Circuit Protection

We offer flexible and programmable synchronous DC/DC buck-boost (step-up/step-down) converters that provide buck mode operation when Vout is less than Vin, boost mode operation when Vout is greater than Vin and buck-boost mode operation when Vout is approximately equal to Vin. The buck-boost switching converter power analog front-end provides a simple, scalable power solution with custom configurations to enable clients to design configurable power supplies in small packages for the targeted end application. Our buck-boost controllers can be used in applications that require efficiency and the ability to generate a regulated output voltage including automotive, USB-C® Power Delivery (PD), battery-powered and industrial applications.
