MAX1832–MAX1835  
High-Efficiency Step-Up Converters with  
Reverse Battery Protection  
General Description  
Features  
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.  
● Reverse Battery Protection for DC-DC Converter  
and Load  
● Up to 90% Efficiency  
● No External Diode or FETs Needed  
● Internal Synchronous Rectifier  
● 4μA Quiescent Current  
● <1μA Shutdown Supply Current  
● +1.5V to +5.5V Input Voltage Range  
● Accurate SHDN Threshold for Low-Battery Cutoff  
These step-up converters operate from a +1.5V to +5.5V  
input voltage range and deliver up to 150mA of load cur-  
rent. 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. In shutdown, the MAX1832/MAX1833 connect  
the battery input to the voltage output, allowing the input  
battery to be used as a backup or real-time clock supply  
when the converter is off (see Selector Guide).  
● BATT Connected to OUT in Shutdown for Backup  
Power (MAX1832/MAX1833)  
● RST Output (MAX1833/MAX1835)  
● Fixed 3.3V/3.0V Output Voltage  
● Adjustable Output Voltage (MAX1832/MAX1834)  
● Up to 150mA Output Current  
● Tiny 6-Pin SOT23 Package  
MAX183_EUT devices are available in a miniature 6-pin  
SOT23 package. The MAX1833ETT30 is available in a  
3mm x 3mm thin DFN package. The MAX1832EVKIT is  
available to speed designs.
