C OM 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.
The output voltage programming range of 2.
2V to 5V, requires only two external resistors via the feedback pin (see Figure 1.
0).
Output load currents of up to 200mA are achievable and the internal MOSFET is capable of switching up to a 1A cu...
