Part Number Description Key Advantages
MAX8569, MAX8569A, MAX8569B 200mA Step-Up Converters in 6-Pin SOT23 and TDFN

Turns off power supply when not in use to save power; increases efficiency by running directly off of batteries.
MAX1947 Low Input/Output Voltage Step-Up DC-DC Converter with Active-Low RESET

Harvests more energy from alkaline cells to extend battery life; high switching frequency reduces external component size.
MAX1722, MAX1723, MAX1724 1.5µA IQ, Step-Up DC-DC Converters in Thin SOT23-5

0.91V startup enables single-cell operation, saving space, weight, and cost.
MAX1832, MAX1833, MAX1834,
...
High-Efficiency Step-Up Converters with Reverse Battery Protection

Simplify electromechanical design with integrated reverse-battery protection; turn off power supply when not in use to save power.
