NCP1403  
15 V/50 mA PFM Step−Up  
DC−DC Converter  
The NCP1403 is a monolithic PFM step-up DC-DC converter.  
This device is designed to boost a single Lithium or two cell  
AA/AAA battery voltage up to 15 V (with internal MOSFET) output  
for handheld applications. A pull-up Chip Enable feature is built  
with this device to extend battery-operating life. Besides, the device  
can also be incorporated in step-down, and voltage-inverting  
configurations. This device is available in space-saving TSOP-5  
package.
