Overview
NCP1597B Buck Regulator - Synchronous 1 MHz, 2 A The NCP1597B is a fixed 1 MHz, high−output−current, synchronous PWM converter that integrates a low−resistance, high−side P−channel MOSFET and a low−side N−channel MOSFET.
The NCP1597B utilizes internally compensated current mode control to provide good transient response, ease of implementation 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 A.
The NCP1597B has features including fixed internal switching frequency (FSW), and an internal soft−start to limit inrush current.
Using the EN pin, shutdown supply current is reduced to 3 mA maximum.
