NCP1597A Buck Regulator - Synchronous 1 MHz, 2.0 A 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 (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, power saving mode and thermal shutdown.
