NCP1593A, NCP1593B Synchronous Buck Regulator 1 MHz, 3 A The NCP1593 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 NCP1593 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 0.6 V and is able to supply up to 3 A of load current. The NCP1593 includes an internally fixed switching frequency (FSW), and an internal soft−start to limit inrush current. Other features include cycle−by−cycle current limiting, 100% duty cycle operation, short− circuit protection, power saving mode and thermal shutdown.
