LM2576T-ADJ Power supply DC DC through long cables is associated with the voltage that is the greater, the longer the cable length and the current drawn by the receiver. Sometimes this fall is so big that the receiver is not working properly. The presented regulator compensates for this by measuring the voltage at the receiver…
Amplifier 4×60 Watts. To its solution was first selected integrated circuit LM3886T. The proposal continued the calculations and the election of the additional components of the integrated circuit and the design of printed circuit connections. To the end amplifier was also designed system of active cooling. In the fourth chapter was made the proposal of…
100W Power Led Driver Circuit Select the suitable type of a power driver, if the lamp with LED of power about 100W supplied from a distribution network 230V. Compare the different options for solution driver. Build a simplified a mathematical model of the used LEDS and the simulation in the environment Matlab-Simulink UCC3813D UCC28180 An…
DC-DC Laboratory Power Supply 0-30V 0-3A LT1074 is a switching regulator type step-down (lowering) with a maximum current of 5 A. Can work with the value of the input voltage up to 60 V version (HV) and the output voltage can be set in the range of 2.5 V – 50 In. Without modifying the…
1KW PFC Circuit UC3855 for its function requires a dc supply voltage of 10 to 20V . His sampling is during normal operation of 17 to 25 ma. The integrated circuit additionally contains the input VCC zener diode of 20V. The maximum current for this diode is, however, only 20 mA [19]. Therefore, it is…
Previously LM2575 (1 amp), and the LM2576 (3 amps) switching regulator ICS sharing about applications that have been LM2575, LM2575 high power mosfet to increase the output current by adding the received power regulator circuits of this type are usually integrated in the upgrade I wanted to share, it’s no wonder. Note: without pictures I…
