4MHz, 500mA Synchronous Step-Down DC-DC Converters in Thin SOT and TDFN
MAX8560/MAX8561/MAX8562
General Description
The MAX8560/MAX8561/MAX8562 step-down DC-DC converters are optimized for applications that prioritize small size and high efficiency.
They utilize 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 is guaranteed up to 500mA, while quiescent current is only 40µA (typ).
Internal synchronous rectification greatly improves efficiency and eliminates the external
