The power supply process for the LAM Technologies unregulated power supply DP1652
LAM Technologies' unregulated power supply DP1652 is a common switching power supply whose working principle is based on the basic principle of switching power supply, which regulates the output voltage by controlling the on-off time of the switch. The following is an introduction to the principle of the unregulated power supply DP1652 from LAM Technologies:
First, the basic principle of switching power supply.
Switching power supply is a kind of power supply equipment that converts alternating current into direct current, and its working principle is based on the law of electromagnetic induction and the development of fully controlled devices. The switching power supply adjusts the output voltage by controlling the on-off time of the switch, so as to achieve the function of voltage stabilization or unregulation. Switching power supplies have the advantages of high efficiency, small size, and light weight, and are widely used in various electronic devices.
Second, the circuit structure of DP1652.
The circuit structure of DP1652 is mainly composed of input circuit, switch tube, transformer, output circuit and feedback circuit.
Input circuit: The role of the input circuit is to convert alternating current to direct current and provide a driving voltage for the switch. The input circuit usually consists of a rectifier bridge, a filter capacitor, and so on.
Switch: The switch is the core component of the switching power supply, which adjusts the output voltage by controlling the on-off time of the switch. The switch transistor used in DP1652 is usually an N-channel MOSFET transistor, which has the advantages of fast on-off speed and good thermal stability.
Transformer: The transformer is an important component in the switching power supply, which converts the input voltage into the output voltage through the principle of electromagnetic induction. The transformer used in the DP1652 usually has an isolation effect, which can ensure the isolation of the output voltage from the input voltage.
Output circuit: The function of the output circuit is to rectify and filter the voltage output of the transformer and output direct current for supply to the load. The output circuit usually consists of rectifier diodes, filter capacitors, etc.
Feedback circuit: The function of the feedback circuit is to sample the output voltage and feed back to the driving circuit of the switch, and adjust the output voltage by controlling the on-off time of the switch. The feedback circuit used in DP1652 usually adopts opto-decoupled isolation feedback structure, which can effectively improve the stability and reliability of the feedback signal.
3. The workflow of DP1652.
The workflow for the DP1652 is as follows:
The input circuit converts alternating current to direct current, providing the drive voltage for the switch.
The switch is switched on and off under the control of the driving circuit, and the output voltage is adjusted by controlling the on-off time of the switch.
The transformer converts the input voltage into the output voltage, and the voltage conversion is realized through the principle of electromagnetic induction.
The output circuit rectifies and filters the voltage output of the transformer and outputs direct current for the load.
The feedback circuit samples the output voltage and feeds it back to the driving circuit of the switch, and adjusts the output voltage by controlling the on-off time of the switch.
