To measure the six-pin switching power supply chip, you must first prepare test tools, such as oscilloscopes, multimeters, etc. Connect the six-pin switching power supply chip to the test tool correctly and pay attention to the correctness of the wiring to avoid reverse connection or short circuit.
Then, according to the test instructions in the data manual, the electrical performance parameters are measured step by step, such as input voltage, output voltage, current, etc.
During the test, attention should be paid to maintaining a stable power supply and load to avoid inaccurate test results due to external interference.
Finally, the quality and performance of the chip are evaluated by comparing the test results with the specifications in the data book.
Measuring a six-pin switching power supply chip requires testing with a multimeter. First, adjust the multimeter to the resistance measurement gear, connect the red pen to the first pin of the chip, connect the black pen to the second pin of the chip, read the resistance value of the multimeter, and then move the black pen to the third pin, continue to read the resistance value, so repeat, measure the resistance value of each pin in turn, to determine whether the resistance of the chip is normal. To confirm whether the chip is working properly. In the measurement process, attention should be paid to choosing the appropriate measurement gear to avoid too large or too small measurement errors.
Measuring six-pin switching power supply chips requires the use of digital voltmeter and multimeter tools.
First, the positive electrode of the digital voltmeter is connected to the output end of the six-pin switching power supply chip, and the negative electrode is connected to the ground wire of the power supply, and the voltage value of the output end is read.
Next, use a multimeter to check whether the resistance values between the various pins of the switch tube, including the source, gate, and drain, are normal. You also need to check whether the voltage between the power input and the ground cable meets the specified range.
Finally, verify and compare according to the technical manual of the chip to confirm whether the chip works normally.
