DC-DC converters are widely used in applications such as telecommunications, automotive, industrial, and medical. REC5-1209SRW/H6/A/SMD is one of the most popular DC-DC converters. This converter topology has a good power density, high reliability, overload operation, high power efficiency, and low airborne noise.

REC5-1209SRW/H6/A/SMD incorporates a fixed Frequently Switched Transformer (FST) technology combined with the Insulated Gate Bipolar Transistor (IGBT) and Pulse Width Modulation (PWM) controller. FST technology enables the converter to operate effectively with high power in a small size.

The working principle of REC5-1209SRW/H6/A/SMD is based on the basic input/output transformer topology. It operates as a buck/boost topology with variable input and output voltage. The input voltage is transformed by a high frequency pulsed signal which is modulated by the PWM controller. The output voltage is determined by the feedback control circuit based on the voltage information collected from the output side. The output voltage can be programmed by changing the PWM signal. The modulation frequency is set usually between 50kHz and 100kHz.

The design of REC5-1209SRW/H6/A/SMD includes a single FST, a dual IGBT, and a PWM controller. The FST is a high frequency, high power density transformer that uses a coil and inner core in parallel. The IGBTs drive the FST and generate the output voltage. The IGBTs control the voltage, current, and switching frequency of the PWM controller. The PWM controller uses the signal from the IGBTs to control the modulating signal and generate the output voltage.

REC5-1209SRW/H6/A/SMD can be used for various applications like telecom, battery system, uninterruptible DC power supply (UPS) system, and vehicular applications. It can provide a stable output voltage even when the input voltage range is wide. It is also very reliable and has low EMF interference.

REC5-1209SRW/H6/A/SMD is suitable for many DC-DC converter applications due to its high power density, reliability, overload operation, high efficiency, and low airborne noise. It can be used in a variety of application fields ranging from telecommunications to automotive, industrial, and medical applications.
