Description

The LX1732 is a compact, high efficiency, step-up DC-DC boost regulator implemented in a BiCMOS process technology. This device features variable frequency operation and a built in N-channel MOSFET power switch for optimal functioning in low voltage portable systems.

Start-up operation is guaranteed from 1.1V inputs (at light load) and the input voltage can be as low as 0.7V after start-up. This attribute allows the LX1732 to operate in an extended powersavings mode, supplying (data) critical system components, even after battery capacity no longer supports normal operation.
