LM3354 Datasheet Regulated 90ma Buck-boost Switched Capacitor DC/dc Converter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM3354 Regulated 90mA Buck-Boost Switched Capacitor DC/DC Converter February 2002 LM3354 Regulated 90mA Buck-Boost Switched Capacitor DC/DC.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.
