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.
