LM3355 - -05 to 5.6 V regulated 50mA buck-boost switched capacitor DC/DC converter
The LM3355 is a CMOS switched capacitor DC/DC converter that produces a regulated output voltage by automatically stepping up (boost) or stepping down (buck) the input voltage.
It accepts an input voltage between 2.5V and 5.5V.
The LM3355 is available with a standard output voltage of 4.1V (ideal fo
