100_W_SWITCHING_REGULATOR

Published:2009/7/20 5:43:00 Author:Jessie | From:SeekIC

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.
