Finally, by exploiting present worth method, rate of return is discussed with respect to present energy cost. Sensitivity analysis shows that only with actual prices of energy and low interest rate, the investment is justified. 展开 关键词: Case study for Tehran Environmental features Rate of ...
3. Cost. Generally, as the RDS(ON) rating goes lower, the cost of the MOSFET goes higher. 5. The dominate MOSFET loss for the MX16171D100 active OR-ing controller is conduction loss due to source-to- drain current to the output load, and the RDS(ON) of the MOSFET. This conduction...
The choice between the two current sensing schemes is largely a design trade-off between cost, power consumption and accuracy. DCR sensing is becoming popular because it saves expensive current sensing resistors and is more power efficient, especially in high current applications. However, current ...

Using Ceramic Input and Output Capacitors Higher value, lower cost ceramic capacitors are now avail- able in small case sizes. Their high voltage rating and low ESR make them ideal for switching regulator applications. However, due to the self-resonant and high-Q character- istics of some ...
By maximizing avail- able voltage and reducing power dissipation (Figure 1), the LT4321 simplifies PD design and reduces power sup- ply cost. It can also eliminate thermal design problems, costly heat sinks, and reduce PC board area. Some designs use ideal diode bridge circuits implemented ...
