The Viking VC5450 chip is even better. 1. Viking VC5450 chip can adjust the temperature higher, up to 125 ° C, compared to dcdc540v chip the maximum temperature is only 85 ° C, so the VC5450 chip has a wider range of application.
2. Viking VC5450 chip has higher power efficiency, so the circuit stability is better, while the reliability is also higher, more suitable for demanding use scenarios. 3. The VC5450 chip has better anti-interference, which can better avoid the influence of power interference and fluctuations on the circuit, compared with the dcdc540v chip, the anti-interference is poor.
ABS, the power chip is better, because it is manufactured in the United States and assembled in Australia
