摘要： An improved circuit and method for decreasing the size and cost of switch mode power supplies is disclosed. In one illustrative example, a feedback circuit for a switch mode power supply is disclosed that includes two error amplifiers. The input of a first error amplifier is coupled to a voltage source associated with a load for the supply, and the input of a second error amplifier is coupled to a current source also associated with the load for the supply. Each one of the error amplifiers includes an adjustable shunt regulator that functions as an amplifier stage and diode. Also, the outputs of the. shunt regulators are connected together. Therefore, the shunt regulator of the first error amplifier can be used to select a voltage limit for the power supply, the shunt regulator of the second error amplifier can be used to select a current set point for the power supply, and the open collector functions of the shunt regulators serve to OR the output signals from the two error amplifiers to produce a signal indicating the loading of the supply. In this manner, an improved feedback circuit for a switch mode power supply is provided that performs the same functions as prior feedback circuits, but has at least three less discrete components (e.g., two diodes and a voltage reference) than the prior feedback circuits. Thus, the disclosed feedback circuit significantly reduces both the size and cost of switch mode power supplies.

摘要： An improved circuit and method for increasing the stability of switch-mode power supplies via frequency fold-back is disclosed. For example, a circuit for increasing the stability of a switch-mode power supply using the compensation signal to control the frequency of the oscillator is disclosed, which includes an operational amplifier that functions to scale the compensation signal. Thus, the switching frequency of the power supply involved is decreased as the load is reduced. This novel use of the compensation signal to control the switching frequency of a switch-mode power supply significantly increases the stability of the power supply as compared to prior switch-mode power supplies. Therefore, the switch-mode power supply may be used for those applications where relatively high stability is desired.

摘要： A contamination resistant connector for medical tubing includes a first portion with a first fluid passage therethrough occluded by a covered normally closed first valve and a second portion with a second fluid passage therethrough. The second portion is conjugate to and releasably attachable to the first portion with the second fluid passage also being occluded by a covered normally closed second valve. The first valve and the second valve are both only uncovered and opened so that the first fluid passage and the second fluid passage are fluidly communicatively connected, and closed and covered by the respective selective conjugate engagement and disengagement of the first portion and the second portion.
