Download Datasheet

  • Description

    The NC2701MA is a 10 A synchronous step-down switching regulator module with a maximum input of 28 V that incorporates CMOS-based DC / DC controller IC, MOSFETs, and 1.0μH (DCR Typ. 4.6 mΩ) inductor. The space-saving power supply design is easy with the NC2701MA. Also, the switching frequency can be adjusted in the range from 250 kHz to 1 MHz by an external resistor. This product is a high-reliability device for industrial application, that has passed both the inspection at high temperature and the reliability test for considering industrial equipment.
