MAX77813

High-Efficiency Buck-Boost Converter

Industry's Best Transient Response Performance with High-Efficiency Across the Load Range


Please check latest availability status for a specific part variant.

Description

The MAX77813 is a high-efficiency buck-boost converter targeted for single-cell Li-ion battery powered applications. The device supports an input voltage range from 2.30V to 5.5V with an output voltage range from 2.60V to 5.14V. The device can support up to 2A and 3A of output current in boost and buck modes respectively. The peak efficiency of 97% allows longer operating time.

The device is designed to support seamless transitions between buck and boost modes. A unique control algorithm allows high-efficiency and outstanding performances in line/load transient responses. The I2C-compatible serial interface provides design flexibility to optimize performance along with protection features. The output voltage can be dynamically adjusted for finer control of system power consumption. The device supports two input current limits selected by ILIM logic input.

The MAX77813 is available in a 1.827mm x 2.127mm, 20-bump wafer-level package (WLP).
