LM3354 - Regulated 90mA Buck-Boost Switched Capacitor DC/DC Converter

Download the LM3354 datasheet PDF. This datasheet also covers the LM3 variant, as both devices belong to the same regulated 90ma buck-boost switched capacitor dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

Description

The LM3354 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.

LM3354 Regulated 90mA Buck-Boost Switched Capacitor DC/DC Converter February 2002 LM3354 Regulated 90mA Buck-Boost Switched Capacitor DC/DC Converter General Description The LM3354 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 LM3354 is available with standard output voltages of 1.8V, 3.3V, 4.1V (ideal for white LED applications), and 5.0V. If other output voltage options between 1.8V and 5.0V are desired, please contact your National Semiconductor representative. The LM3354’s proprietary buck-boost architecture enables up to 90mA of load current at an average efficiency greater than 75%.
