MC34063A DC-DC Converter SMD IC Wires It has a rectangular casingThe MC34063A Series is a monolithic control circuit containing the primary functions required for DCtoDC converters. These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver, and high current output switch. This series was specifically designed to be incorporated in inStepDown and StepUp and VoltageInverting Applications with a minimum number of
