Overview
LM3355 Regulated 50 mA Buck-Boost Switched Capacitor DC/DC Converter
December 2001
LM3355 Regulated 50mA Buck-Boost Switched Capacitor DC/DC Converter
General Description
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 for white LED applications).
If other output voltage options between 1.
8V and 4.
1V are desired for other applications, please contact your National Semiconductor representative.
The LM3355’s proprietary buck-boost architecture en...
