Create a design and simulate using EE-Sim tools: MAX77813EWP33+
The MAX77813EWP33+ 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 MAX77813EWP33+ is available in a 1.827mm x 2.127mm, 20-bump wafer-level package (WLP).Feature
