MAX1733 Datasheet (Maxim) - Low-Voltage / Step-Down DC-DC Converters in SOT23

MAX1733, Low-Voltage / Step-Down DC-DC Converters in SOT23

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)

MAX1733 Features

* makes the MAX1733/ MAX1734 excellent high-efficiency alternatives to linear regulators in space-constrained applications. Internal synchronous rectification greatly improves efficiency and eliminates the external Schottky diode required in conventional step-down converters. Both devices also include
