Low-Voltage, 400mA Step-Down  
DC-DC Converters in SOT23  
General Description  
Features  
The MAX1920/MAX1921 step-down converters deliver  
over 400mA to outputs as low as 1.25V. These convert-  
ers use a unique proprietary current-limited control  
scheme that achieves over 90% efficiency. These  
devices maintain extremely low quiescent supply current  
(50µA), and their high 1.2MHz (max) operating frequency  
permits small, low-cost external components. This combi-  
nation makes the MAX1920/MAX1921 excellent high-  
efficiency alternatives to linear regulators in space-  
constrained applications.  
♦ 400mA Guaranteed Output Current  
♦ Internal Synchronous Rectifier for >90% Efficiency  
♦ Tiny 6-Pin SOT23 Package  
♦ Available in 6-Pin TDFN Package (MAX1920)  
♦ Up to 1.2MHz Switching Frequency for Small  
External Components  
♦ 50µA Quiescent Supply Current  
♦ 0.1µA Logic-Controlled Shutdown  
♦ 2V to 5.5V Input Range  
Internal synchronous rectification greatly improves effi-  
ciency and eliminates the external Schottky diode  
required in conventional step-down converters. Both  
devices also include internal digital soft-start to limit  
input current upon startup and reduce input capacitor  
requirements.  
♦ Fixed 1.5V, 1.8V, 2.5V, 3V, and 3.3V Output  
Voltages (MAX1921)  
♦ Adjustable Output Voltage (MAX1920)  
The MAX1920 provides an adjustable output voltage  
(1.25V to 4V). The MAX1921 provides factory-preset  
output voltages (see the Selector Guide). Both are  
available in space-saving 6-pin SOT23 packages. The  
MAX1920 is also available in a 6-pin TDFN package.
