· 12W DC DC Efficient power supply solution LM25011AMYX

The manufacturer of LM25011AMYX is Texas Instruments. 6-42V Wide Vin, 2A Constant-On Time Buck Regulator with Adjustable Current Limit. Description for the LM25011The LM25011 constant on-time step-down switching regulator features all the functions needed to implement a low-cost, efficient, buck bias regulator capable of supplying up to 2 A of load current. This high-voltage regulator contains an N-Channel Buck switch, a startup regulator, current limit detection, and internal ripple control. The constant on-time regulation principle requires no loop compensation, results in fast load transient response, and simplifies circuit implementation. The operating frequency remains constant with line and load. The adjustable valley current limit detection results in a smooth transition from constant voltage to constant current mode when current limit is reached, without the use of current limit foldback. The PGD output indicates the output voltage has increased to within 5% of the ex...

· How to troubleshoot and repair the BOSHIDA DC power module?

Firstly, before troubleshooting, it is necessary to understand the working principle and basic structure of the DC power module. DC power modules are usually composed of input terminals, output terminals, inductors, capacitors, transformers, rectifier circuits, etc. Common faults include abnormal output voltage, abnormal output current, overload protection triggering, short circuit protection triggering, and abnormal input voltage,etc.The following are the troubleshooting and maintenance steps for the DC power module:1. Check the input voltage to ensure it is normal. If the input voltage is abnormal, it is necessary to check whether the power input terminal has good contact and whether there is loose contact or burning at the input terminal.2. Check if the output terminal is wired correctly and if there are any short circuits or open circuits. If there is a short circuit or open circuit at the output end, it is necessary to repair or replace the output wire.3. Check if the output vol...

· How to choose switching power supply？

Why are switching power supplies prone to malfunctions? Be sure to pay attention to these details when choosing! Some customer friends only focus on a few important parameters such as power, output voltage, efficiency, etc. and then hastily complete the selection when choosing a switching power supply. Finally, due to neglecting some small details, the power supply malfunctioned shortly after use.For example, the factory building has an indoor environment that is not exposed to sunlight or rain, but is filled with metal dust; the application environment of beauty and teaching instruments is good, but there are strict requirements for noise; the equipment in the suburbs is powered from the power grid, and there is significant harmonic interference in the power grid. Faced with these special factors, choosing a conventional and universal switching power supply is very risky, and the failure rate of the power supply is thus increased.Let's talk about the hidden dangers of these often ov...
