The input voltage ranges from 1.6V to 6.0V, allowing for a wide selection of system battery voltages. Start-up operation is guaranteed at 1.6V input The LX1742 is capable of achieving output voltages as high as 25V and the output voltage is easily programmed using two external resistors in conjunction with the feedback pin. The LX1742 has an additional feature for simple dynamic adjustment of the output voltage (i.e., up to 15% of the nominal output voltage).
