In the Xbox game marketplace is rivaling Sony PS 2, Nintendo GameCube and Sega Dreamcast. Power Supply (PSU) to the Xbox includes a fan. Xbox power provides output in the form of dc (DC) and must be

40V Regulated Power Supply based TIP42A and LM317

40V Regulated Power Supply based TIP42A and LM317
This is a 40V Regulated Power Supply, built using IC LM317 as regulator and TIP42A as electric current amplifier. Component part:  Regulated Power Supply R1 = 3R9 1 or 2W R2 = 22R R3 = 6K8 R4 = 220R R5 = 4K7 C1 = 3300µF/50V or 4700µF/50V C2,C5 = 100nF C3 = 10µF/63V C4 = 220µF/50V D1 = Diode bridge 100V 4A D2 = 1N4002 D3 = LED IC1 = LM317T Q1 = TIP42A SW2 = SPST Mains switch

1.5-25V Power supply with preregulator

1.5-25V Power supply with preregulator
This circuit using KR142EN12 (analog - LM317 ) ic regulator that can handle load currents up to 2 amperes. For higher currents can be used IC LT1083/84/85 that each can handle currents 7/5/3A. 2000uF capacitor C3 is selected from the calculation of the current 1 Ampere. Resistor R9 is used as a current sensor to an ammeter. (more…)
