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 s.
