MC33341DR2G [Onsemi]

The MC33341 is a monolithic regulation control circuit that isspecifically designed to close the voltage and current feedback loops inpower supply and battery charger applications. This device features theunique ability to perform source high–side, load high–side, sourcelow–side and load low–side current sensing, each with either aninternally fixed or externally adjustable threshold. The various current sensing modes are accomplished by a means of selectively using the internal differential amplifier, inverting amplifier, or a direct input path. Positive voltage sensing is performed by an internal voltage amplifier. The voltage amplifier threshold is internally fixed and can be externally adjusted in all low–side current sensing applications. An active high drive output is provided to directly interface with economical optoisolators for isolated output power systems. This device is available in 8–lead dual–in–line and surface mount packages.
