The MAX8561ETA step-down dc-dc converter is optimized for applications that prioritize small size and high efficiency. It utilizes a proprietary hysteretic-PWM control scheme that switches with fixed frequency and is adjustable up to 4MHz, allowing customers to trade efficiency for smaller external components. Output current of MAX8561ETA is guaranteed up to 500mA, while quiescent current is only 40A (typ).
Internal synchronous rectification of MAX8561ETA greatly improves efficiency and eliminates the external Schottky diode required in conventional step-down converters. Built-in soft-start eliminates inrush current to reduce input capacitor requirements. The MAX8561ETA features logic-controlled output voltage.
The MAX8561ETA is available in space-saving 8-pin 3mm x 3mm Thin DFN packages.
