LTC3441 Li-Ion to 5V at 600mA Boost Converter with Output Disconnect

The LTC3441 is a high efficiency, fixed frequency, buck-boost DC/DC converter that operates efficiently from input voltages above, below or equal to the output voltage. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for single lithium ion or multi-cell applications where the output voltage is within the battery voltage range.
