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 ou
