NCP1595, NCP1595A,
NCP1595C
1 MHz, 1.5 A Synchronous
Buck Regulator
The NCP1595/A/C family are fixed 1 MHz, highâoutputâcurrent,
synchronous PWM converters that integrate a lowâresistance,
highâside Pâchannel MOSFET and a lowâside Nâchannel 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 softâstart to limit inrush currents. Using the EN
pin, shutdown supply current is reduced to 3 mA maximum.
Other features include cycleâbyâcycle current limiting,
shortâcircuit protection and thermal shutdown.
