General Description
The MAX8640Y/MAX8640Z step-down converters are optimized for applications where small size, high efficiency, and low output ripple are priorities. They utilize a proprietary PWM control scheme that optimizes the switching frequency for high efficiency with small external components and maintains low output ripple voltage at all loads. The MAX8640Z switches at up to 4MHz to allow a tiny 1μH inductor and 2.2μF output capacitor. The MAX8640Y switches at up to 2MHz for higher efficiency while still allowing small 2.2μH and 4.7μF components. Output current is guaranteed up to 500mA, while typical quiescent current is 28μA. Factory-preset output voltages from 0.8V to 2.5V eliminate external feedback components.
Internal synchronous rectification greatly improves efficiency and replaces the external Schottky diode required in conventional step-down converters. Internal fast soft-start eliminates inrush current so as to reduce input capacitor requirements.
The MAX8640Y/MAX8640Z are available in the tiny 6-pin, SC70 (2.0mm x 2.1mm) and μDFN (1.5mm x 1.0mm) packages. Both packages are lead-free.
