4MHz, 500mA Synchronous Step-Down  
DC-DC Converters in Thin SOT and TDFN  
General Description  
Features  
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 cus-  
tomers to trade efficiency for smaller external compo-  
nents. Output current is guaranteed up to 500mA, while  
quiescent current is only 40µA (typ).

40µA (typ) Quiescent Current  
Adjustable Output Voltage from 0.6V to 2.5V  
Logic-Controlled Output Voltage (MAX8561)  
Drives External Bypass FET (MAX8562)  
Internal synchronous rectification greatly improves effi-  
ciency 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 MAX8561 features logic-  
controlled output voltage, while the MAX8562 drives an  
external bypass FET.

The MAX8560 is available in a 5-pin Thin SOT23 pack-  
age. The MAX8561/MAX8562 are available in space-  
saving 8-pin 3mm x 3mm Thin DFN packages.
