NCP1597A  
1 MHz, 2.0 A Synchronous  
Buck Regulator  
The NCP1597A family are fixed 1 MHz, highoutputcurrent,  
synchronous PWM converters that integrate a lowresistance,  
highside Pchannel MOSFET and a lowside Nchannel MOSFET.  
The NCP1597A utilizes current mode control to provide fast transient  
response and excellent loop stability. It regulates input voltages from  
4.0 V to 5.5 V down to an output voltage as low as 0.8 V and is able to  
supply up to 2.0 A.

MARKING  
DIAGRAM  
The NCP1597A includes an internally fixed switching frequency  
(FSW), and an internal softstart to limit inrush currents. Using the EN  
pin, shutdown supply current is reduced to 3 mA maximum.  
Other features include cyclebycycle current limiting,  
shortcircuit protection, power saving mode and thermal shutdown.
