The circuits. To produce any output voltage, an external feedback resistors can be added. The sLM2576 is a Switching Regulator that can produce 15, 12, 5, 0r 3.3V output voltage from maximum supply voltage of 60V or 40V. This LM2476 featured with voltage reference, switch and feedback path for use in either the negative boost or the buck saturation voltage […]

In the circuit the rotary converter is nothing more than a second motor which is acting as a generator. The tools motor performed this function with the static converter, but at the cost of some loss of power. The idler motor is under no physical load but it cleans up the signal with the rotary converter. The only difference on […]

Triode for alternating current,TRIAC, is an electronic component that can control power in two direction in an AC circuit. The figure (a) shows the block construction and schematic symbol of TRIAC. The TRIAC is operated like two SCRs in parallel connection in opposite direction like shown in figure (b). Here is the figure of TRIAC: A TRIAC can be triggered […]

Silicon Diode for Alternating Current, SIDAC, is a multilayer silicon semiconductor switch. This component is triggered by voltage and can be operated as bidirectional swtch. Usually, this SIDAC is used in cheap high voltage power supply or ignition circuits. Figure below shows SIDAC block construction, schematic symbol and geometric construction : The SIDAC has leakage current(Idrm) less than 5 µA […]

Diode for alternating current is a trigger diode which conducts current only after the DIAC reach the breakdown voltage. The breakdown voltage of DIAC is 30 V. It has construction like an open base NPN transistor. The DIAC can be used in many application such as motor speed controls and light dimmers circuit. Figure below shows the DIAC block construction, […]

The diagram below shows us a simple block construction of an SCR (upper left) and its schematic diagram (upper right). The lower diagram shows us the operation of a PNPN device can best visualized as a specially coupled pair of transistor. When a proper gate signal is applied to the base of the NPN transistor, the connections between the two […]

The LM9070 is a 5V, 3% accurate voltage regulator which have 250mA low-dropout. The regulator has an active low delayed reset output flag feature. This feature can be used to reset microprocessor system on turn-ON and in the event that the regulator output falls out of regulation for any season. Before the reset output can return high, an external capacitor […]
