LM3355  
Regulated 50mA Buck-Boost Switched Capacitor DC/DC  
Converter  
General Description  
Features  
±
n Regulated VOUT with 3% accuracy  
n Standard output voltage of 4.1V  
n Custom output voltages available from 1.8V to 4.1V in  
100 mV increments  
The LM3355 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 LM3355 is available with a standard output voltage of  
4.1V (ideal for white LED applications). If other output volt-  
age options between 1.8V and 4.1V are desired for other  
applications, please contact your National Semiconductor  
representative.  
n 2.5V to 5.5V input voltage  
n Up to 50 mA output current  
>
n
75% average efficiency  
n Uses few, low-cost external components  
n Very small solution size  
The LM3355’s proprietary buck-boost architecture enables  
up to 50 mA 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 375 µA typical operating current  
n 2.3 µA typical shutdown current  
n 1 MHz switching frequency (typical)  
n Architecture and control methods provide high load  
current and good efficiency  
The LM3355 is available in a 10-pin MSOP package. This  
package has a maximum height of only 1.1 mm.  
n MSOP-10 package  
n Over-temperature protection  
The high efficiency of the LM3355, 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.  
Applications  
n White LED display backlights  
See the LM3352 for up to 200mA of output current.  
n 1-cell Lilon battery-operated equipment including PDAs,  
hand-held PCs, cellular phones  
n Flat panel displays  
n Hand-held instruments  
n NiCd, NiMH, or alkaline battery powered systems
