The Operation of the Step Down chopper is as follows: • When the chopper is in ON state, load voltage is equal to the source voltage. • When the chopper is in OFF state, the load current flows through the diode. As a result load terminals are short circuited by the diode. WebThe MAX1836/MAX1837 high-efficiency buck (step-down) con¬verters 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 125mA (MAX1836) or 250mA (MAX1837). bardani manchebo
