NCP1077A Description
Available in a two different pin-out of the very mon PDIP-7 package, the NCP107xuz offers a high level of integration, including soft-start, frequency-jittering, short-circuit protection, skip-cycle, a maximum peak current set-point, ramp pensation, and a dynamic self-supply (DSS, eliminating the need for an auxiliary winding). Unlike other monolithic solutions, the NCP107xuz is quiet by nature: during nominal load...
