MAX1734 - Step-Down DC-DC Converter

Download the MAX1734 datasheet PDF. This datasheet also covers the MAX1734EUK18 variant, as both devices belong to the same step-down dc-dc converter family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • makes the MAX1733/ MAX1734 excellent high-efficiency alternatives to linear regulators in space-constrained.

19-1586; Rev 0; 7/00 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 eliminates the external Schottky diode required in conventional step-down converters.
