REC5-2409DRWZ/H4/A/SMD/CTRL-R is DC-DC converters which utilizes a special design intended for capacitor-free DC-DC applications. The converter module is mostly used for applications requiring boosted voltage, current regulation, and high efficiency power conversion. The DC-DC converter module features an integrated high-efficiency, out-of-regulation (OOR) protection feature and is specifically designed to provides boost voltage regulation up to an output voltage of 24V. The module is also designed to provide noise immunity against power surges and short circuits. The device features a conduction-cooled SMD construction using an enhanced high-temperature thermal interface to reduce thermal losses. The device requires very low-ESR input capacitors, allowing for reduced component size and cost. The device offers an adjustable input voltage range of 5V (5V max) and operates at up to 94% peak efficiency for a load current of 1A. The REC5-2409DRWZ/H4/A/SMD/CTRL-R DC-DC converter can be used to regulate power levels for a range of applications. The device can be used for powering small remote sensors, and for providing voltage and current regulation in automotive, telecom and computer systems. The device can also be employed for providing a DC power output from AC sources, eliminating the need for an AC power adapter. It can also be used in battery charging applications. The device can be used in distributed power systems where multiple boards each need their own power supply and need to be powered from the same source. The DC-DC converter is based on a buck-boost converter topology and comprises a switch, coupled with an inductor and an output diode. The switch works based on the PWM (Pulse Width Modulation) method, where the width of pulses is changed to control the desired voltage output. The output voltage is regulated by the duty cycle of the switch drive pulse, which is created using an external analog regulator. The pulse width of the switch drive pulse is changed by varying the voltage applied to the feedback pin of the module. The control signal applied to the feedback pin is compared to an internally generated reference voltage. When the voltage applied to the feedback pin is greater than the internal reference voltage, the duty cycle of the switch drive pulse increases, thus increasing the output voltage. On the other hand, when the voltage applied to the feedback pin is less than the internal reference voltage, the duty cycle of the switch drive pulse decreases, thus decreasing the output voltage. For the device to have a stable output, the input voltage must remain constant. Therefore the input voltage range of the module is limited to ensure that the input voltage does not exceed the maximum allowed voltage. Additionally, the device features several protection features including over-temperature, overload, and short-circuit protection. The device is also provided with an external soft-start function that prevents current surges and ripple on power-up, ensuring quiet and seamless power transition. The device is encapsulated in a 3mm x 3mm x 0.9mm surface mount package and is RoHS compliant. The REC5-2409DRWZ/H4/A/SMD/CTRL-R DC-DC converter is an efficient and reliable power solution that provides voltage and current regulation and helps reduce cost and size. The device is widely used in a range of applications, making it an ideal choice for powering a variety of loads.
