A DC/DC converter is a voltage converter which can effectively output fixed voltage after converting input voltage. These converters are essential for stabilizing power in various electronic systems. They are categorized into Boost, Boost & Buck, and Buck types, adopting PWM or PFM control based on demand.
PWM control provides high efficiency with low noise, while PFM control excels in low power consumption for long-term use under small loads. Currently, these converters are widely used in mobile devices, digital cameras, and portable media players.

Frequently Asked Questions (FAQ)
Q1: What is the main difference between PWM and PFM control in these converters?
PWM control offers high efficiency and excellent noise/ripple suppression. PFM control is advantageous for low power consumption during long-term use, especially under light load conditions.
Q2: Can I use a non-isolated buck converter for sensitive equipment?
While possible, it is not recommended for precious loads. In a non-isolated converter, a failure could cause high input voltage to pass directly to the output. Isolated converters are recommended for maximum safety.
Q3: What precautions should be taken for inductive loads like motors?
For inductive loads (motors, magnetic valves, speakers), we recommend using a power supply that is 3-5 times the rated power of the load to handle start-up surges.
Q4: Does the converter have built-in protection against short circuits?
Most buck-boost and step-down models include standard short-circuit and overcurrent protection. However, step-up models may require external fuses at the input end to prevent damage during a short circuit.
Q5: Is the aluminum casing suitable for outdoor use?
Yes, the gold-colored small aluminum casing is specifically designed to be high-temperature resistant and highly reliable for outdoor and industrial applications. Many models also feature IP67 waterproofing.
Q6: Can isolated power supplies support negative voltage?
Yes, isolated power supplies can support negative voltage input, and the output can be configured for either positive or negative voltage. Ensure the 0V line is connected to the red wire and the negative line to the black wire.
