Description

General part information

MAX1833 Series

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. 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).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.ApplicationsBattery BackupCordless PhonesDigital CamerasHandheld InstrumentsLocal 3.3V to 5V SuppliesMedical Diagnostic EquipmentPagersPC CardsRemote Wireless Transmitters
