Will be very useful, especially in electronic laboratory power supply dc voltage between 0 and 0 to 350V current is adjustable from 400mA. 4 on the power stage MOSFET spw20n60s5 control lm712 op amp used on the floor. Clean for a healthy voltage rectified mains voltage is not used directly in the power output 600mA 270V 270V ac required trofo rectified dc voltage is controlled around 380v.
Power supply 350volt under the full power of 152W 400mA low power may seem to be, but this is the highest voltage for the current low-voltage, more current can be drawn, but in this case, MOSFETs in the more power will be spent actually before I share “Regulated power supply for the relay bypass circuit” is added yield more is high.
NOTICE is working with 350 volt high voltage regulator circuit capacitor connection Observe caution + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles

LM3886 Car Amplifier Circuit DC to DC Converters SG3525 Project
Stereo auto amp project amplifier 2 for LM3886 for supply sg3525 used the converter input voltage 12v … 14.4 v between output and 2 × 30 volt transformer for the FT140/77 toroidal ring core (inner diameter of 0.9 outer diameter 1.4) used PROM winding three 1mm wire 2 × 5 connected in parallel to the secondary winding is wound round 2 × 12 rounds of 0.8mm wire. In addition to auto amp vu meter made by lb1403’s.
