Conv DC-DC Single 100V 4-Pin(3+Tab) TO-3

The Microsemi ESP Switching Regulator Is a unique hybrid transistor circuit, specifically designed, constructed and specified for use, in high current switching regulator application. The designer is thus relieved of one of the most time consuming, tedious and critical aspects of switching regulator design: choosing the appropriate switching transistors and commutating diode and empirically determining the optimum drive and bias conditions. Switching regulators, when compared to conventional regulator result in significant reductions in size, weight and internal power losses and a major decrease in overall cost. Using the Microsemi PIC600 series, the designer can achieve further improvements in size, weight, efficiency and costs. At the same time, because of the PIC600 series design and packaging, the designer is aided in overcoming two of the most significant drawbacks to switching regulators: noise generation and slow response time; there is, in fact, no diode reverse recovery spike. The PIC600 series switching regulators are designed and characterized to be driven with standard integrated circuit voltage regulators. They are completely characterized over their entire operating range of -55°C to +125°C The devices are enclosed in a special 3-pin TO-3 package, hermetically sealed for high reliability. The hybrid circuit construction utilizes thick film resistors on a beryllia substrate for maximum thermal conductivity and resultant low thermal impedance. All of the active elements in the hybrid are fully passivated.
