DC DC Converters: REC15-245.1SZ/H2 Application Field And Working Principle

DC DC converters are devices that convert a direct current (DC) voltage to a different DC voltage. They typically are used to provide a wide range of voltages from a single supply, to operate at high efficiency, to filter out undesirable variations in voltage, or to improve the stability and control of the output voltage. The REC15-245.1SZ/H2 is a 15 watt, single-stage switching-mode buck regulator with a wide input voltage range of 6 to 36VDC, and an adjustable output voltage of 0.8 to 32VDC, supporting a wide variety of applications.In general, switching-mode converters work by using continuous long and short pulses of switching devices to connect and disconnect components from the power source. This allows the transformer or inductor to store energy and shape the output voltage.The REC15-245.1SZ/H2 is particularly suitable for applications that require low-noise, adjustable voltage outputs and high efficiency, such as LED lighting, microelectronics, chargers, and telecom.The device’s internal monitoring circuitry constantly monitors output and input voltages, controlling the switching devices to adjust output voltage. In case of an overload or short circuit, the internal safety circuit will automatically cut off the output. The device is also protected to operate over-temperature, exceeding the 25°C threshold.The REQ15-245.1SZ/H2 converter features an adjustable soft-start time, auto restart on a power-on, and a wide temperature range from -40° to +85°C. The device offers an active PFC solution, low EMI noise, and has a MTBF (mean time between failure) of 497 khours. It also has a wide input to output isolation range of 4KVdc, four times higher than the UL/IEC 60950, making it suitable for a wide range of critical applications with safety requirements.The REQ15-245.1SZ/H2 switching converter uses a buck regulator topology to reduce input voltage to the required level. The switching devices are connected in series with an inductor, each connected to the input and output of the circuit. The time spent according to the on/off command is controlled by a pulse control circuit, ensuring that the power delivered to the output is proportional to the control signal.In a buck regulator, the time spent in the on/off command is known as the duty cycle. When the duty cycle is higher, more power is transferred to the output, increasing the output voltage. The duty cycle is controlled by an internal reference voltage. The REC15-245.1SZ/H2 has a 200kHz switching frequency, ensuring fast response time and high efficiency.The device uses a metal-oxide-semiconductor field-effect transistor (MOSFET) with an integrated current-limiting circuit to control its output current. The current limiting circuit will shut down the converter in the event of an overload or short circuit. The device also features undervoltage and overvoltage protection, as well as thermal shutdown, ensuring safe operation in a variety of operational scenarios.The REC15-245.1SZ/H2 is a high-performance, cost-effective solution for low-noise adjustable voltage outputs, and applications requiring stability and control of the output voltage. With its adjustable soft-start time, low EMI noise, wide temperature range, excellent isolation, and built-in protection, the REC15-245.1SZ/H2 offers a reliable and safe solution for many different applications.
