Features

* Tiny SC70 and µDFN Packages 500mA Guaranteed Output Current 4MHz or 2MHz PWM Switching Frequency Tiny External Components: 1µH/2.2µF or 2.2µH/4.7µF 28µA Quiescent Current Factory Preset Outputs from 0.8V to 2.5V ±1% Initial Accuracy Low Output Ripple at All Loads Ultrasonic Skip Mode Down to 1mA Loa

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 t
