LM3352 Regulated 200 mA Buck-Boost Switched Capacitor DC/DC Converter
General Description
The LM3352 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 LM3352 is available in three standard output
voltage versions: 2.
5V, 3.
0V and 3.
3V.
If other output
voltage options between 1.
8V and 4.
0V are desired, please contact your National Semiconductor representative.
The LM3352’s proprietary buck-boost architecture enables up to 200 mA of load cur...
