DC–DC converters are essential components that allow electrical devices to function in a wide range of environments. The REC3-1215SRW/H6/A/SMD is a type of converter specifically designed for applications that require high efficiency and reliable performance. This article provides an overview of the application fields and working principle of this device.

The REC3-1215SRW/H6/A/SMD is a highly efficient DC-DC converter suitable for a wide range of applications, including automotive and industrial applications such as motor drives, gate drives, and power supplies. The device has a wide input voltage range of 4.5 to 20 V and an adjustable output voltage range of 1.25 to 15 V with a maximum output power of 15 W. The high efficiency of the device is achieved by a synchronous rectification technique, which significantly reduces switching losses and improves thermal performance.

The key feature of the REC3-1215SRW/H6/A/SMD is its integrated power stage consisting of two half-bridge switches connected in a push-pull configuration. These switches are driven by an integrated driver that can produce high switching speeds and provide smooth transitions between the on and off states of the device. This allows the device to achieve high efficiency and precise regulation of the output voltage at low input voltages.

The working principle of the REC3-1215SRW/H6/A/SMD is based on the principle of pulse-width modulation (PWM). During the on and off states of the device, the integrated driver produces pulses of different widths to control the switching of the power stage. Pulses of a shorter width cause the switch to be turned on, while pulses of longer widths turn it off. This results in an accurate output voltage regulation, even at lower input voltages.

In addition to the adjustable output voltage, the device also features a number of protection features, such as over-current, over-voltage, and short-circuit protection. The device also has an input reverse-polarity protection feature, which ensures that the device will remain safe in the event of a reversed power supply connection.

To ensure maximum efficiency and reliable performance, the device includes a number of solution-level features, such as input ESD protection, output ripple filtering, and thermal protection. In addition, the device is also compliant with a number of automotive industry standards, including AEC-Q100-0002 and ISO7637-2.

Overall, the REC3-1215SRW/H6/A/SMD is a highly efficient and reliable DC–DC converter suitable for a wide range of applications. The device provides an adjustable output voltage range of 1.25 to 15 V, which allows for precise output voltage regulation. In addition, the device features a number of protection features to ensure maximum efficiency and reliable performance. Finally, the device is compliant with a number of automotive industry standards, which makes it suitable for use in automotive applications.
