ON Semiconductor introduced the NCP3101 and NCP3102 – two new switching regulators designed to simplify embedded designs in high density applications. The new level of integration provided by these devices enables customers to replace DC/DC modules with embedded designs to reduce system cost while increasing power density. The NCP3102 and NCP3101 are both integrated switching regulators that address the industry’s growing need for efficient high power density designs.
NCP3102 is a 10 A synchronous switching regulator that enables high efficiency power conversion from a +5 V or +12 V supply. The internal 8 milliohm high-side FET (HS-FET) and 8 milliohm low-side FET (LS-FET) enable efficiencies greater than 92 % for typical buck applications. The NCP3102 also features an internal voltage reference of 0.8 V for sub 1 V operation which is now being required.
NCP3101 is a 6 A synchronous switching regulator that is pin-for-pin compatible with the NCP3102. This pin compatibility allows design engineers to scale their power solutions without having to redesign their printed circuit board (PCB). In many designs that use an FPGA for example, the final power requirements are not known until late in the design cycle. By offering true design flexibility, the NCP3101 allows the design engineer to scale up or scale down the power requirement based on the system need.
