19-1802; Rev 2; 4/05 EVAALVUAAILTAIOBNLEKIT High-Efficiency Step-Up Converters with Reverse Battery Protection MAX1832–MAX1835 General Description The MAX1832–MAX1835 are high-efficiency step-up converters with complete reverse battery protection that protects the device and the load when the battery is reversed. They feature a built-in synchronous rectifier, which allows for over 90% efficiency and reduces size and cost by eliminating the need for an external Schottky diode. These step-up converters operate from a +1.5V to +5.5V input voltage range and deliver up to 150mA of load current. The MAX1833EUT/MAX1835EUT (SOT devices) have a fixed 3.3V output voltage. The MAX1833ETT30 (TDFN device) has a fixed 3.0V output voltage. The MAX1832/MAX1834 have adjustable outputs from +2V to +5.5V.
