MAX1836ETT33+

The MAX1836ETT33+ is a 24V internal switch, 100% duty cycle, step-down converter in 6 pin TDFN package. This high efficiency step down converter provides a preset 3.3V 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 125mA. The unique current limited control scheme, operating with duty cycles up to 100%, minimizes the dropout voltage (120mV at 100mA). 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. It is ideal for low cost, low power and space sensitive applications. The MAX1836 is also used in 9V battery systems, distributed power systems, backup supplies and 4mA to 20mA loop power supplies.
