DC DC Converters

DC DC converters are electronic devices used for converting a direct current (DC) voltage from one level to another. They are capable of taking a wide input voltage range and making it suitable for applications to make sure that a load will be powered correctly. The PA01S2412A model is a DC-to-DC converter specifically designed for ultra-wide input voltage range (18V – 75V) and high efficiency and output voltage stability.

Application Field

The PA01S2412A model is ideal for applications requiring stable output voltage convert where highly efficient switching converters power components can be used. They are used in telecommunications systems, industrial test and measurement equipment, computers, vehicle data recorders, ATMs, and onboard data acquisition and telemetry systems.

Work Principle

The DC-to-DC converter operates based on buck-boost topology. This type of converter involves two states, the Buck Mode and the Boost Mode. During the Buck Mode, the input DC voltage is lowered and the output current is increased, while in the Boost Mode, the input DC voltage is increased and output current is decreased.

The converter utilizes an N-channel MOSFET as the main switching device and a current source to achieve fast transient response. The current source is based on the LM317/337 series high-performance current source. It produces a regulated output voltage in both Buck and Boost modes.

The PA01S2412A can operate in both step-down (Buck) and step-up (Boost) modes. It uses a analog input voltage control signal to adjust the output voltage in a range between 0.8V and 64V. The output voltage is regulated and has low noise operation.

Features

The PA01S2412A commes with the following features:

• Ultra-wide input voltage range (18V – 75V)
• High efficiency (up to 95%)
• Fast transient response time (up to 250 ns)
• Output voltage regulation from 0.8V to 64V
• Low quiescent current (<0.2A)
• Output voltage ripple and noise (200μVrms typ)
• Built-in short-circuit protection

Conclusion

The PA01S2412A is an ideal DC-to-DC converter for applications requiring high efficiency and low noise operation. It is easy to implement in a variety of system design solutions and uses an analog input voltage control to adjust the output voltage in the range of 0.8V to 64V. The PA01S2412A is a great choice for those dealing with the challenges of noisy and unreliable supplies, such as industrial and automotive applications.
