LM2678 (5A)DC to DC step down voltage regulator.(Switching power supply regulator) Wide input voltage 8Vdc to 40Vdc. Part number: – LM2678-3.3 (3.3Vdc output) – LM2678-5.0 (5Vdc output) – LM2678-12 (12Vdc output) – LM2678-ADJ (1.2Vdc to 37Vdc output) Component list – 45uF 50V electrolytic capacitor – 0.47uF – 6TQ045S high speed schottky diode – Output 100V [...]
The circuit in Figure 1 steps down a nominal -12V to a regulated -5V. It allows -5V to come up only after a separately regulated +5V has come up, and if the +5V collapses, it automatically shuts down the -5V. This is useful in ±5V supplies for A/D and D/A converters, which often require such [...]
The step down converter is the power unit to make the output voltage which is lower than the input voltage. The converter which was made this time makes +2V to +10V output voltage with the input voltage of +12V. Because it makes the limitation value of the input electric current about 1.3A, the maximum with [...]
