LM3352 - Regulated 200 mA Buck-Boost Switched Capacitor DC/DC Converter

Download the LM3352 datasheet PDF. This datasheet also covers the LM3 variant, as both devices belong to the same regulated 200 ma buck-boost switched capacitor dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

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.

LM3352 Regulated 200 mA Buck-Boost Switched Capacitor DC/DC Converter September 1999 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 current at an average efficiency greater than 80%.
