LTC1626, a step-down converter that operates from single Li-Ion cell, is described.
Step-down DC/DC converter
The LTC1626 is a low voltage, high efficiency, monolithic step-down DC/DC converter featuring an input supply voltage range of 2.5V to 6V, which makes it ideal for single-cell Li-Ion applications. A built-in low RDS(ON) switch provides high efficiency and allows up to 0.6A of output current. The LTC1626 incorporates automatic power saving Burst Mode operation to reduce gate-charge losses when the load current drops. With no load, the converter draws only 160μA and in shutdown it draws a mere 1μA, making it ideal ...
