MAX1733/MAX1734
Low-Voltage, Step-Down DC-DC Converters in SOT23
General Description
The MAX1733/MAX1734 step-down DC-DC converters deliver over 250mA 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 (40µA), and their high 1.
2MHz (max) operating frequency permits small, low-cost external components.
This combination of features makes the MAX1733/ MAX1734 excellent high-efficiency alternatives to linear
regulators in space-constrained applications.
Internal synchronous rectification greatly improves efficiency and eliminat...
