For module power supply products with trim or adj (adjustable) output pins, the output voltage can be adjusted within a certain range through resistance or potentiometer, and the general adjustment range is ± 10%.Module power supplyFor the trim output pin, the center of the output potentiometer and

First, evaluate the module power requirements of the systemFor the electronic system, the module power demand not only focuses on the input voltage, output voltage and current, but also considers the power consumption, power efficiency, transient response of power to load changes, tolerance of key e

When purchasing switching power supply modules, everyone will encounter the problem of how to choose specifications. We usually recommend that customers choose according to the actual needs of the enterprise, and pay attention to whether they purchase a switching power supply module with power failu

1. Isolation:1. Safety isolation: strong current and weak current isolation, IGBT isolation drive, surge isolation protection, lightning isolation protection (such as isolation protection of medical electronic equipment in contact with human body)2. Noise isolation: (isolation of analog circuits and

1. Adopt a mature power supply topologyThe design of the power module should use mature power topologies as far as possible. These topologies have passed the test of time and are mature and reliable. For example, the constant voltage input dcdc power supply mode t of 1-2W selects the Royer cir

dc means direct current, and dcdc is a device that converts electrical energy of one voltage value into electrical energy of another voltage value in a DC circuit. constituted as one.The dcdc power supply module is a newly developed miniaturized power switch module. It adopts microelectronic technol

The influence of heating on the power supply is affected by conversion compliance, circuit board layout and heat dissipation. In modular power or electronic systems, air cooling is often used as a heat sink. Therefore, radiators and axial fans are widely used.Because the working principle of the axi

Power transformer is a kind of soft magnetic electromagnetic component. Because of its functions of power transmission, voltage conversion and insulation isolation, it has been widely used in power supply technology and power electronics technology.When the transmission power is different, the desig

The digital switching power supply has strong controllability. Planning the digital switching power supply circuit and preparing for operation will help improve the accuracy of the digital switching power supply planning and avoid problems in the work. This paper will analyze and introduce what is d

Many people think that the noise of inverter power supply is due to equipment failure, and blind inspection and replacement cause a lot of waste. Our inspection should also be correct, find the problem, and then solve it to prevent it from happening again.1. Due to external interference, after carry
