General Description

The LM3354isa CMOS switched capacitor DC/DC con-
verter that producesa regulated output voltageby automati-
cally steppingup (boost)or stepping down (buck) the input
voltage.It acceptsan input voltage between 2.5V and 5.5V.
The LM3354is available with standard output voltagesof
1.8V, 3.3V, 4.1V (idealfor white LED applications), and 5.0V. other output voltage options between 1.8V and 5.0V are
desired, please contact your National Semiconductor repre-
sentative.
The LM3354’s proprietary buck-boost architecture enablesto 90mAof load currentatan average efficiency greater
than 75%. Typical operating currentis only 375µA and the
typical shutdown currentis only 2.3 µA.
The LM3354is availableina 10-pin MSOP package. This
package hasa maximum heightof only1.1 mm.
The high efficiencyofthe LM3354, low operating and shut-
down currents, small package size, andthe small sizeofthe
overall solution make this device idealfor battery powered,
portable, and hand-held applications.
See the LM3352forupto 200mAof output currentor the
LM3355forupto 50mAof output current.
Features
Regulated VOUT with ±3% (5.0V, 4.1V, and 3.3V
options)or ±4% (1.8V option) accuracy Standard output voltagesof 1.8V, 3.3V, 4.1V, and 5.0V Custom output voltages available from 1.8Vto 5.0Vin
100 mV increments with volume order 2.5Vto 5.5V input voltage range Upto 90mA (5.0V, 4.1V, and 1.8V options)or 70mA
(3.3V option) output current >75% average efficiency Uses few, low-cost external components Very small solution size 375µA typical operating current 2.3µA typical shutdown current1 MHz typical switching frequency Architecture and control methods provide high load
current and good efficiency MSOP-10 package Over-temperature protection
Applications
White LED display backlights 1-cell Lilon battery-operated equipment including PDAs,
hand-held PCs, cellular phones Flat panel displays Hand-held instruments Li-Ion, NiCd, NiMH,or alkaline battery powered systems
