IA4815S Datasheet/PDFDC DC converters, such as the IA4815S, are used to transform electrical energy. Typically, these converters take bursts of energy from one source, such as alternating current (AC) or direct current (DC) power supplies, and convert it into a regulated, constant frequency and voltage for use by appliances and devices such as computers, printers, and other electronic equipment. The IA4815S is a type of DC-DC converter specifically designed for use in audio/visual applications.
The IA4815S is a step-down converter that takes an input voltage of 48-120V DC and provides a constant output voltage of 12V DC across its outputs. It uses a switch-mode buck converter topology with integrated Control IC for feedback and protection. The device is adjustable and can be used for outputs up to 1.5A. It also features voltage feed-forward and over-voltage protection to ensure reliable and safe operation in audio/visual applications.
The working principle behind the IA4815S converter is based on the basic theory of operating a switch-mode power supply. This type of converter uses electronic switching, instead of linear regulators, to control the transfer of energy from a higher voltage DC source to a lower voltage DC load. In the case of the IA4815S, this is 12V DC from a 48-120V DC input. This regulates the output voltage and allows for efficient power conversion.
The internal components of the IA4815S consist of a pulse-width modulation (PWM) controller, an inductor, a transformer, and two capacitors. The PWM controller is used to generate a high frequency pulse-width modulation signal. This signal is then applied to the converter, allowing it to rapidly switch on and off to control the output voltage. The inductor and transformer are used to store and transfer energy from the input voltage to the output voltage. The capacitors act as a filter for the output voltage, and ensure an even output voltage.
The IA4815S is an ideal solution for many audio/visual applications. It provides a reliable and efficient output voltage for applications that require regulated 12V DC. Its integrated Control IC enables reliable and safe operation, while its voltage feed-forward and over-voltage protection make it ideal for varied input voltage ranges. The IA4815S is an ideal solution for audio/visual applications such as monitor displays, TV displays, and AV systems.
