NCP1595C  
1 MHz, 1.5 A Synchronous  
Buck Regulator  
The NCP1595/A/C family are fixed 1 MHz, highoutputcurrent,  
synchronous PWM converters that integrate a lowresistance,  
highside Pchannel MOSFET and a lowside Nchannel MOSFET.  
The NCP1595/A/C 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 1.5 A.  
The NCP1595/A/C 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 and thermal shutdown.
