Datasheet NC2780 Synchronous 34V Input Buck Switching Regulator (Controller) FEATURES GENERAL DESCRIPTION • Input Voltage (Maximum Rating): 4.0 V to 34 V (36 V) • Start-Up Voltage: 4.5 V • Output Voltage: 0.7 V to 5.3 V • Feedback Voltage Tolerance: 0.64 V ± 1 % • Quiescent Current: Typ. 15 µA (PFM at no load) The NC2780 is a CMOS-based controller-type buck switching regulator that operates using external high-side and low-side NMOSFETs. Equipped with a PFM function, it achieves high efficiency even at light loads, enabling low consumption in the system. Also, the switching frequency can be adjusted in the range of 250 kHz to 1 MHz by an external resistor.
