Product Preview  
2.5 A Boost Regulator  
with Bypass Function  
The NCP6868 is a synchronous boost converter. It is designed  
primarily to boost new generation low-voltage Li-Ion batteries (silicon  
anode-like) embedded into cell and smart phones. The objective is to  
guarantee a minimum output voltage even in the case for which the  
battery voltage is below the minimum voltage required by the system.  
The device features a Bypass mode coupled with a Boost mode. It is  
capable to drive a continuous load up to 2.5 A and it operates at

a switching frequency of 2.5 MHz. An I C serial control can also be  
enabled for configuring the output voltage and peak current limit. The  
NCP6868 is available in a space saving, low profile 1.8 × 1.8 mm  
CSP-16 package.
