Chassis Finish Considerations for EMI
Texas InstrumentsIt is a known fact that the electrical contact of the seams in a chassis containing high-frequency switching signals must be sealed in order to provide EMI containment. This application report describes the issues and pitfalls created by the metal finish and the design of the chassis mating surfaces (seams).
IC Temp Sensor Provides Thermocouple Cold-Junction Compensation (Rev. B)
Texas InstrumentsTwo circuits using the LM335 for thermocouple cold-junction compensation have been described. With asingle room temperature calibration these circuits are accurate to ±3/4°C over a 0°C to 70°C temperaturerange using J or K type thermocouples. In addition a thermocouple amplifier using an LM335 for coldjunctioncompensation has been described for which worst case error can be as low as 1°C p

UCC38C42 Family of High-Speed BiCMOS Current-Mode PWM Controllers
Texas InstrumentsSince their introduction in the mid 1980?s the bipolar UC3842 family of Pulse width modulation (PWM)controllers has grown to become the most widely-used control strategy in the power supply industry. [1] The reasons for success are quite clear the devices feature an elegantly simple yet very effective control architecture they use only 8 pins they can drive MOSFET gates directly and they offer
