MAX1837 Datasheet | Maxim Integrated

Description The MAX1836/MAX1837 high-efficiency step-down converters provide a preset 3.3V or 5V output voltage from supply voltages as high as 24V. Using external feedback resistors, the output voltage can be adjusted from 1.25V to VIN. An internal current-limited switching MOSFET delivers load currents up to 125m A (MAX1836) or 250m A (MAX1837). The unique current-limited control scheme, operating with duty cycles up to 100%, minimizes the dropout voltage (120m V at 100m A). Additionally, this control scheme reduces supply current under light loads to 12μA. High switching frequencies allow the use of tiny surface-mount inductors and output capacitors. The MAX1836/MAX1837 step-down converters with internal switching MOSFETs are available in 6-pin SOT23 and 3mm x 3mm TDFN packages, making them ideal for low-cost, low-power, space-sensitive applications.
