Presentation Transcript

  1. Components Used • Rectifier,60v,20a,t0-220schottky,w/CNTR tap common cathode [MOTOROLA mbr2060ct / DOIDES inc sbl2060c • Inductor,100 uh,2.8 amp ac • Cap,100mf,100v,AERL,(SIEME • Cap,1000mf,50v,AERL,(ill cap ) • Lm2576T-ADJ • POT,2K,2W,.25% • RES,5.6K,2W,5%,CC

  2. Vin 15 V and Vout ( 5 to 13.5 V)

  3. Vin 25 V and Vout 20 V • The wave form is measure across the Ground point and Lm2576 Pin 2 • That is before Inductor and Cout.

  4. Make the wire that coming out from Lm2576 Pin2 long enough to go through the donut and got the top wave form. • These double pulse is shown when the longer wire is replaced • Those double pulse go away by replacing shorter wire between Lm2576 Pin 2 and Cout.

  5. With Vin 15 V • Probe Measured across the load • By adjusting R1 pot voltage will vary between 5 to 13 V with 15 V input. • In beginning 10 ohms 50 W load was first used. Then replaced with two 10 ohms 50 W parallel and series with 2 ohm 50W
