DC DC Converters

A DC DC Converter is a device that changes one DC voltage level into another. This type of device is commonly used in a variety of applications, including automotive, aerospace, telecom, consumer electronics and more. The REC5-0505SRW/H6/A/SMD/CTRL is a DC DC converter that is used for a variety of applications.

Application Field

The REC5-0505SRW/H6/A/SMD/CTRL is a low-cost, high-efficiency, wide input voltage range DC DC converter that can be used for a variety of applications. It can be used for automotive, aerospace, telecom, consumer electronics, renewable energy, medical, industrial, computer, networking, and other applications requiring an efficient, reliable and cost-effective power conversion solution. It is an ideal power solution for applications that require low voltage input and high current output.

The REC5-0505SRW/H6/A/SMD/CTRL can provide a wide range of output voltages, from 0.8V to 26V, with an adjustable output voltage range of 0.3V to 24V. It is equipped with a high efficiency synchronous rectifier circuit that provides excellent energy efficiency at low input voltages and high output currents. The device is also capable of providing fast transient response, low output noise, and low EMI.

Working Principle

The REC5-0505SRW/H6/A/SMD/CTRL utilizes a standard buck-boost converter circuit with synchronous rectification. A power switch on the input side is driven by a pulse width modulation (PWM) signal generated by the control circuitry. This PWM signal is then used to turn the input switch ON and OFF which in turn adjusts the output voltage. When the output voltage is higher than the input voltage, the basic buck-boost principle is active and the power switch is turned OFF when the output voltage is too low. When the output voltage is lower than the input voltage, the power switch is turned ON and the output voltage is regulated.

The PWM signal is provided to the power switch by a pair of gate drivers, one for the high side and one for the low side. The gate drivers ensure that the power switch is driven at the appropriate voltage level and with the correct duty cycle. The output voltage is regulated by adjusting the duty cycle of the PWM signal.

The REC5-0505SRW/H6/A/SMD/CTRL also utilizes an optional Synchronous Rectifier (SR) circuit for improved efficiency. The SR circuit replaces the power switch on the input side with a pair of bidirectional, high speed switches with low on-resistance that conduct when the output voltage is below the input voltage. This allows for a higher efficiency during input-output voltage conversions.

Conclusion

The REC5-0505SRW/H6/A/SMD/CTRL is a low-cost, high-efficiency DC DC converter that can be used for a variety of applications. It can provide a wide range of output voltages with adjustable output voltage ranges. It is equipped with a synchronous rectifier circuit for improved efficiency when converting from low to high voltage. The device\'s PWM signal is regulated to adjust the output voltage, and an optional synchronous rectifier circuit is used for a higher efficiency rate. These features make the REC5-0505SRW/H6/A/SMD/CTRL a reliable and cost-effective solution for a variety of applications.
