NCP1546  
1.5 A, 170 kHz, Buck  
Regulator with  
Synchronization Capability  
The NCP1546 is a 1.5 A buck regulator IC operating at a  
2
fixed−frequency of 170 kHz. The device uses the V t control  
http://onsemi.com  
architecture to provide unmatched transient response, the best overall  
regulation and the simplest loop compensation for today’s high−speed  
logic. The NCP1546 accommodates input voltages from 4.5 V to 40 V  
and contains synchronization circuitry.  
MARKING  
DIAGRAM  
The on−chip NPN transistor is capable of providing a minimum of  
1.5 A of output current, and is biased by an external “boost” capacitor  
to ensure saturation, thus minimizing on−chip power dissipation.  
Protection circuitry includes thermal shutdown, cycle−by−cycle  
current limiting and frequency foldback.
