NCP1595, NCP1595A,

NCP1595C

1 MHz, 1.5 A Synchronous

Buck Regulator

The NCP1595/A/C family are fixed 1 MHz, high−output−current,

synchronous PWM converters that integrate a low−resistance,

high−side P−channel MOSFET and a low−side N−channel 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 soft−start to limit inrush currents. Using the EN

pin, shutdown supply current is reduced to 3 mA maximum.

Other features include cycle−by−cycle current limiting,

short−circuit protection and thermal shutdown.
