MAX77511

10V Input, Quad-Phase Configurable, 3A/Phase, High-Efficiency Buck Converter

Extend Battery Life and Save Space with Configurable Quad-Phase Buck Converter Operating from a 1s/2s Li+ Battery


Please check latest availability status for a specific part variant.

Description

The MAX77511/MAX77711 are four-phase, 3A/phase, configurable single to quad output, step-down buck regulators for 1s/2s Li+ battery inputs. Output voltage is programmable through an I2C interface between 0.25V and 5.2V. The buck has four combinable 3A switching phases (Φ) for up to four regulated outputs. Phases are configurable to higher-current multiphase outputs: 4Φ, (3+1)Φ, (2+2)Φ, (2+1+1)Φ, or (1+1+1+1)Φ.

Six GPIOs can be purposed for I/O expansion or buck status and control. Pseudo-random spread-spectrum modulation suppresses EMI. Soft-start, soft-stop, and DVS slew times are programmable with I2C. MAX77711 offers a 300mA linear regulator.

MAX77511/MAX77711 are available in a 64-bump, 3.54mm x 3.54mm wafer-level package (WLP).
