100_W_SWITCHING_REGULATOR

Published:2009/7/20 5:43:00 Author:Jessie

Chief advantage of switching-mode regulator is relatively low power dissipated in series regulating transistor. Circuit provides 20 v d-c output, constant within 0.2 v, for loads up to 5 amp. Input 60-cps voltage may vary 10 v above and below 40 v. Operating tempera lure range is -25 to +50°C. Driver transistors Q7 and Q8 operate as switches that are saturated when driven with positive pulses from mvbr.-Texas Instruments Inc., Transistor Circuit Design, McGraw-Hill, N.Y., 1963, p 468.   (View)

FEEDBACK_CHOKE_CUIS_RIPPLE

Published:2009/7/20 5:24:00 Author:Jessie

Choke L1, placed in feedback path from Q1 to Q2, holds down ripple in current supplied to load through Darlington amplifier Q2-Q3. Choke acts as if it were in series with load even though carrying only a fraction of load current.-J. T. Quatse, Feedback Choke Reduces Power Supply Ripple, Electronics, 39:13, p 74.   (View)

PRECISION_12_V_200_MA_SUPPLY

Published:2009/7/20 5:21:00 Author:Jessie

Regulation is less than 0.001% for 10% change in line voltage. Sharp current limiting at 300 ma is provided by R1 and D3. Darlington connection for series regulator gives current gain of 10,000 at 100 ma, so normal variation of reference amplifier collector current is only 10 microamp over full range of output current.- Iransistor Manual, Seventh Edition, General Electric Co., 1964, p 232.   (View)
