Tiny 500mA, 4MHz/2MHz Synchronous Step-Down DC-DC Converters
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 ponents 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 ponents. Output current is...
