MAX8640Y Datasheet (Maxim Integrated Products) - 4MHz/2MHz Synchronous Step-Down DC-DC Converters

MAX8640Y, 4MHz/2MHz Synchronous Step-Down DC-DC Converters

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
