PSPICE Modeling of Commercial ICs for Switch-Mode Power Supply (SMPS) Design and Simulation

PSPICE modeling of a commercial LED driver IC (TOP245P) and PC817A optocoupler is proposed for the switch-mode power supply (SMPS) (applicable to LED driver) design and simulation. An analog behavioral model of the TOP245P IC including the shunt regulator, undervoltage(UV) detection, over-voltage(OV) shut-down and SR flip-flop is developed by using PSPICE. The empirical equation of PC817A curre...

Switch Mode Power Supply (SMPS) Topologies

This application note, which is the first of a two-part series, explains the basics of different SMPS topologies. Applications of different topologies and their pros and cons are also discussed in detail. This application note will guide the user to select an appropriate topology for a given application, while providing useful information regarding selection of electrical and electronic compone...

Switch Mode Power Supply Design Constraints for Space Applications

This paper describes the design trade-offs presented in DC-DC power converters used in space applications. The major concern, in the design of power supplies for space applications, is to obtain a very high reliability level, which can be very difficult to quantify, considering the relatively low production quantities involved. Space converters have to deal with radiation effects, vacuum enviro...

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
