REC7.5-1209DRW/H2/A/M/SMD/CTRL-R

DC-DC converters are electronic systems used to convert electric energy from one type of DC voltage to another type of DC voltage. REC7.5-1209DRW/H2/A/M/SMD/CTRL-R is a type of DC-DC converter. It is an isolated, regulated DC/DC converter that is designed for a voltage range of 5.0V to 12.0V and a power of up to 9.0 watts.

The REC7.5-1209DRW/H2/A/M/SMD/CTRL-R is typically used in applications such as industrial automation, data acquisition, telecommunication, automotive, and telecommunications. It can also be used for medical device applications since its power levels are low and its environmental and input parameters are tightly regulated. It features a very low power consumption and high efficiency, an LED indicator for predicting a fault, and a wide input voltage range. The device is also RoHS compliant.

The REC7.5-1209DRW/H2/A/M/SMD/CTRL-R contains a controller, a power MOSFET, an inductor, and a transformer to convert the input DC voltage to an output DC voltage. It also contains protection features such as over-current, over-voltage, and over-temperature protection. The device also has built-in short-circuit protection and output voltage limitation features. These features ensure the safety of the converter.

The controller circuitry of the REC7.5-1209DRW/H2/A/M/SMD/CTRL-R contains a voltage regulator that regulates the output voltage. This voltage regulator is coupled with the input voltage and output voltage feedback loop to ensure controlled responses to various output load variations. The power MOSFETs switch current through the inductor that stores and then releases energy as other energy sources transfer power. The transformer provides galvanic isolation, and its primary is coupled with the control MOSFETs to drive the secondary winding of the transformer with a square wave. The power transfer between primary and secondary is made possible by the transformer and a capacitor, creating a step-down voltage conversion.

The REC7.5-1209DRW/H2/A/M/SMD/CTRL-R also features a frequency control circuit that reduces EMI. This circuit operates at 400 kHz and uses high-frequency PWM to control the output voltage, allowing for a high switching frequency with low noise and ripple. The device also has an adjustable soft-start feature, which helps to reduce inrush current during power-up, thus ensuring smooth start-up.

In summary, the REC7.5-1209DRW/H2/A/M/SMD/CTRL-R is a type of DC-DC converter that is designed for a voltage range of 5.0V to 12.0V and a power of up to 9.0 watts. It features high efficiency, protection features, and frequency control to reduce EMI. It is typically used in applications such as industrial automation, data acquisition, telecommunication, automotive, and telecommunications.
