Buck Converter High-Efficiency, Synchronous 4 A, 6 A, 2 MHz NCP1594A, NCP1594B The NCP1594 is a high output current synchronous PWM converter that integrates two N channel Power MOSFETs. The NCP1594 utilizes externally compensated voltage mode control to provide good transient response, ease of implementation, and excellent loop stability. It regulates input voltages from 2.9 V to 6.0 V down to an output voltage as low as 0.6 V and is able to supply up to 4.0 A of load c.
