MAX1920/MAX1921
Low-
Voltage, 400mA Step-Down DC-DC Converters in SOT23
General Description
The MAX1920/MAX1921 step-down converters deliver over 400mA to outputs as low as 1.
25V.
These converters 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 combination makes the MAX1920/MAX1921 excellent high-efficiency alternatives to linear regulators in space-constrained applications.
Internal synchronous rectification greatly improves efficiency and eliminates the external Schottky diode requ...
