DC DC Converters - R1D12-1209/HP Application Field and Working Principle

DC DC converters, such as the R1D12-1209/HP, are especially designed for; electrical systems with highly sensitive components in; industrial, telecommunications, medical and military; applications. These converters provide highly reliable,; accurate power to sensitive components while; minimizing component size and cost.

The R1D12-1209/HP is a DC/DC converter, designed to be used in AC main-powered systems, and able to convert a wide range of input voltage from 6.5 to 40V to a very low voltage output, usually ranging from 0.6 to 12V. The wide range of input and output voltage makes this converter perfect for applications where the voltage input is varying. The converter is also specially designed with built in overvoltage protection, output over-current protection and output short-circuit protection, to make it suitable for applications in industrial, medical and military areas.

The R1D12-1209/HP DC/DC converter consists of the primary side (the input side) and the secondary side (the output side). The primary side circuits are responsible for rectifying and filtering the AC input voltage, and for providing a solid voltage to the secondary side. The secondary side of the R1D12-1209/HP is composed of one boost switch, a control IC, a pair of P-FETs, a low dropout regulator (LDO), a transformer, a diode bridge rectifier, and some capacitors and inductors to create the desired output voltage. The components of the secondary side of the converter are components of the control and regulation system which controls the output voltage.

The power management system in the R1D12-1209/HP converter includes an on-board power saving mode and a low power standby mode. The power saving mode is activated by detecting the dynamic changes in input voltage, such as the moment when the input voltage drops to a certain threshold voltage. When the input voltage is low, the power saving mode increases the PWM and the power of the converter will be reduced, thus reducing the power consumption of the system. The power saving mode allows energy to be saved and will also prolong the battery life of the system.

The R1D12-1209/HP DC/DC converter has a variety of input and output voltage, wide operating temperature range and high efficiency, strongly making it perfect for applications in industrial, medical and military. It has built-in protection mechanisms. The power management system has a power saving mode and a low power standby mode. By controlling the power consumption of the system, it can save a lot of energy and prolong the battery life of the system.
