DC-DC converters are power conversion devices used to convert an input voltage to a desired output voltage, typically with a regulated output and high efficiency. The REC5-4809DRWZ/H2/A/SMD-R is one such DC-DC converter used in monitor, industrial, automotive, and consumer electronics applications. It is a feature-rich, highly efficient device with great power density.

The REC5-4809DRWZ/H2/A/SMD-R is a buck converter with an input voltage of 9-36 VDC and an adjustable output voltage of 0.9-32 VDC. The output current is rated up to 5A, with an efficiency up to 92% for a 3A load. It is a synchronous step-down converter with PWM/PFM Control and an Auto-Restart/Over-Voltage Protection. The chip integrates an FGA9 dual-phase operation for low ripple, low EMI, and low noise.

The REC5-4809DRWZ/H2/A/SMD-R is a highly efficient and low cost device suitable for many applications, including desktop computers, consumer electronics, industrial controls, automotive electronics, and communications products. It operates over a wide temperature range of -40 to +125 C, and is rated for 2000V high surge voltage. The device also supports remote sensing to compensate for output voltage drop caused by trace resistance.

The REC5-4809DRWZ/H2/A/SMD-R is designed to operate in a wide range of input voltages, from 9V up to 36V. It has an internal voltage reference, so the output voltage is determined by the ratio of two resistors (R1 and R2) connected to either the FB or Vin pins. This allows the user to adjust the output voltage from 0.9V to 32V. In addition, the device can be optimized for either higher efficiency or lower noise by using either PWM or PFM control modes.

The REC5-4809DRWZ/H2/A/SMD-R incorporates a sophisticated protection circuitry that includes over-temperature protection, over-voltage protection, and automatic restart. The device uses two-phase operation with synchronous rectification, reducing the losses associated with rectifying circuits and improving the output ripple and power density. In addition, it supports remote sensing to compensate for output voltage drop caused by trace resistance.

In summary, the REC5-4809DRWZ/H2/A/SMD-R is a highly efficient, low cost, and feature-rich DC-DC converter used in a wide range of applications. It offers an adjustable output voltage, wide input voltage range, low noise operation, and robust protection features. It is rated for 2000V surge voltage and offers high power density with its two-phase operation. It is an excellent choice for any application requiring DC-DC conversion.
