DC-DC converters are power devices used to change the voltage from one level to another, setting up a closed loop system which regulates the output voltage. REC5-0512SRW/H2/C/M/SMD is one such device belongs to the family of DC-DC converters.This converter is highly reliable and efficient and is capable of switching loads up to 10A. It is featured with an Automatic Output Circuit Protection ensuring safety measure and also features an input volatge range of 8V to 72V. It also has a comparatively high efficiency rate of 95% and low line output ripple of 100mV p-p.The REC5-0512SRW/H2/C/M/SMD converter is mostly used in automotive applications as it is highly efficient and reliable than other DC-DC converters. It is used in automobile electronic systems such as engine control, emission control, traction control, stability control and other active safety. It is also widely used in industrial systems, inverters in solar system, 3G/4G antenna equipment, medical and telecom systems.The REC5-0512SRW/H2/C/M/SMD employs a quasi-resonant switching method working principle, which helps in keeping the components at low cost and enables stable performance as compared to other types of DC-DC converters. To understand its working principle, lets consider its simplified schematic diagram.It consists of an input voltage supply and a transformer. An MOSFET switch is connected between the input supply and the transformer which combines the quantifying capabilities of a PWM controller and the high frequency operation of a pulse transformer. When the switch comes in contact with the MOSFET, the input voltage is converted into a high frequency, high voltage (HV) pulse and applied to the primary winding of the transformer. The pulse is applied to the gates of the secondary winding, generating the required output voltage.At low frequency, the generated pulse results in higher energy losses, affecting the converter’s efficiency. Thus, the REC5-0512SRW/H2/C/M/SMD employs a quasi-resonant switching technique in which the frequency of the pulse is varied by an internal resonance of the transformer’s primary and secondary coil. This reduces the losses and helps in improving the efficiency of the device.The REC5-0512SRW/H2/C/M/SMD converter has a wide input voltage range, low output ripple and high efficiency, which makes it the preferred choice for automotive applications. Apart from this, the automatic output circuit protection ensures safe operations of the device. Its quasi-resonant switching technique helps in improving efficiency and reducing energy losses. With all these features, the REC5-0512SRW/H2/C/M/SMD is able to handle large loads, making it the perfect choice for any industrial and application system.
