DC-DC converters are necessary electronic components when building a power supply system. Most of the DC-DC converters are used to convert the input voltage to an output voltage that is adjusted and regulated according to the specific requirements of the application. DC-DC converters can be either isolated or non-isolated, and the latter are more common in basic supplemental power systems and power protection solutions.

The PTH12060L series of DC-DC converters is an example of a non-isolated DC-DC converter, specifically a buck converter. It is designed for applications that require efficient conversion of relatively large DC input voltage to a smaller DC output voltage and optimized for use in linear and switching power supply systems.

The PTH12060L’s application field is primarily for medium to high-power applications such as IT and telecom industries, consumer and instrumentation, industrial electronics and renewable energy solutions. It also offers a 0.5 percent line regulation to ensure a stable output voltage, and low voltage drops on the conduction path to maintain a higher efficiency. The common input voltage range for the PTH12060L series is between 18V to 36V, and the output voltage is adjustable from 0.9V to 15V, with a power output range of 60W while operating within the temperature range of -40˚C to +85˚C.

The PTH12060L series is an integrated and compact DC-DC converter with built-in heat dissipating design. This ensures the safe cooling during operation and minimizes the amount of external components required. The working principle of the series is a buck converter, meaning it will reduce the voltage through a combination of energy storage and transfer to output.

The PTH12060L series utilizes a combination of external components such as inductors, capacitors, diodes, and MOSFETs along with its power switches to reduce the input voltage levels down to the desired output. When the input voltage supplied exceeds the desired output voltage, then it must be appropriately regulated. The energy transfer is generally done through inductors, capacitors, and transistors. Using a step-down method, the output voltage is regulated and maintained by a feedback loop.

The feedback loop monitors the output voltage, allowing the system to make the necessary adjustments in order to ensure that the output remains consistent and stable. It includes a voltage control loop that monitors the output voltage and alters the frequency or duty cycle of the output to keep the output voltage within an accepted range. This allows for the PTH12060L series to remain the most efficient and powerful DC-DC converter available.
