LM3354

Regulated 90mA Buck-Boost Switched Capacitor DC/DC

Converter

General Description

Features

n Regulated V_OUTwith 3% (5.0V, 4.1V, and 3.3V

The LM3354 is a CMOS switched capacitor DC/DC con-

verter that produces a regulated output voltage by automati-

cally 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 repre-

sentative.

options) or 4% (1.8V option) accuracy

n Standard output voltages of 1.8V, 3.3V, 4.1V, and 5.0V

n Custom output voltages available from 1.8V to 5.0V in

100 mV increments with volume order

n 2.5V to 5.5V input voltage range

n Up to 90mA (5.0V, 4.1V, and 1.8V options) or 70mA

(3.3V option) output current

75% average efficiency

The LM3354’s proprietary buck-boost architecture enables

up to 90mA of load current at an average efficiency greater

than 75%. Typical operating current is only 375 µA and the

typical shutdown current is only 2.3 µA.

n Uses few, low-cost external components

n Very small solution size

n 375 µA typical operating current

n 2.3 µA typical shutdown current

n 1 MHz typical switching frequency

n Architecture and control methods provide high load

current and good efficiency

The LM3354 is available in a 10-pin MSOP package. This

package has a maximum height of only 1.1 mm.

The high efficiency of the LM3354, low operating and shut-

down currents, small package size, and the small size of the

overall solution make this device ideal for battery powered,

portable, and hand-held applications.

n MSOP-10 package

n Over-temperature protection

See the LM3352 for up to 200mA of output current or the

LM3355 for up to 50mA of output current.

Applications

n White LED display backlights

n 1-cell Lilon battery-operated equipment including PDAs,

hand-held PCs, cellular phones

n Flat panel displays

n Hand-held instruments

n Li-Ion, NiCd, NiMH, or alkaline battery powered systems
