NCP1597A
1 MHz, 2.0 A Synchronous
Buck Regulator
The NCP1597A 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 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.

The NCP1597A includes an internally fixed switching frequency
(F SW ), and an internal soft ? start to limit inrush currents. Using the EN
pin, shutdown supply current is reduced to 3 m A maximum.
Other features include cycle ? by ? cycle current limiting,
