DC-DC converters are used to convert a direct current (DC) input voltage to a DC output voltage that is different from the input voltage. In most applications, the output voltage is required to be lower than the input voltage and stronger than the input voltage. The most commonly used DC - DC conversion devices include flyback converters, buck converters, and boost converters. Each type of converter has its respective applications and working principles.

The SRAH-05A1200 converter is a step-down buck converter that can convert a high input voltage of 9V to 12V to an output voltage of 5V. This converter is designed to have an input current of 1.2A and is capable of providing an output current of up to 1.2A. It also has an over-current protection and soft start feature.

Application Field of SRAH- 05A1200

The SRAH- 05A1200 can be used in different applications with different requirements. It is suitable for applications requiring low output voltage, such as LED drivers, computer peripherals, power supplies for communication equipment, and DC motors. It is also suitable for applications that require high efficiency and power density, such as computers, program-controlled switches, and medical equipment.

In addition, its wide input voltage range and low power consumption make it suitable for portable applications, such as personal electronic devices and smartphones.

Working Principle of SRAH- 05A1200

The SRAH-05A1200 converter uses a buck topology, which is highly efficient and can provide high output current. It is based on the principle of inductive-switching-capacitive-regulation (LSCR).

The device uses a power switch, inductor and capacitor to complete the conversion. When the switch is turned on, input voltage is applied to the inductor. This creates an energy storage in the form of a magnetic field. The capacitor acts as a buffer to smooth the output voltage. When the switch is turned off, the energy stored in the inductor is released to the output through the capacitor.

As the energy is released to the output, the voltage across the inductor reduces, allowing the inductor to be quickly switched off. In this way, the output voltage is regulated to be lower than the input voltage.

The device also features an over-current protection and a soft-start feature to ensure safe and reliable operation. The over-current protection senses any abnormal input current and shuts the device off to protect it from damage. The soft-start feature ensures that the device starts up smoothly without causing any sudden increase in input current.
