DC DC Converters refer to devices or circuits that allow for the conversion of voltage or current from one level or form to another. Anything from voltage or current regulation, voltage or current isolation, switching, or signal conversion might be included under the DC DC converter umbrella. The REC5-4815DRWZ/H2/A/M/SMD/CTRL is one such device and is an SMD (surface mount device) offering 15V output with up to 1V input. It is a step-down converter capable of delivering up to 5 amps of output current. The barrier to entry and the cost for power electronics has generally been high, as they require additional components for safety. The REC5-4815DRWZ/H2/A/M/SMD/CTRL skips the extra components to keep cost and complexity low, while still providing excellent levels of safety, as it meets multiple safety standards i.e. CB, cUL and EN60950-1. The REC5-4815DRWZ/H2/A/M/SMD/CTRL\'S Application fieldThe application field of the REC5-4815DRWZ/H2/A/M/SMD/CTRL is very versatile due to its wide range of features. It can be used in conditions where there is electromagnetic interference, as its filtering technology eliminates interference from external sources. In terms of temperature, the REC5-4815DRWZ/H2/A/M/SMD/CTRL is capable of withstanding temperatures as low as -40°C and as high as +85°C. It can also be used to provide cost efficient, high quality auxiliary power sources for automotive applications.The REC5-4815DRWZ/H2/A/M/SMD/CTRL Working PrincipleThe heart of REC5-4815DRWZ/H2/A/M/SMD/CTRL working principle is its buck converter topology. A buck converter uses an inductor to transfer energy to the output as the duty cycle of the switch is varied. At a low duty cycle, the output voltage is low, and at a high duty cycle, the output voltage is high. The switching of the buck converter is done by an internal pulse width modulation (PWM) circuit and a low voltage transistor. The PWM circuit varies the on-time of the low voltage transistor, which ultimately determines the output voltage.The buck converter circuit also contains a feedback loop which helps to stabilize the output voltage. This feedback loop consists of an error amplifier, which operates in comparator mode and compares the actual output voltage to the programmed reference voltage. This error voltage is then used by the error amplifier to control the duty cycle of the PWM signal, thus regulating the output voltage.In summary, the REC5-4815DRWZ/H2/A/M/SMD/CTRL is a versatile step-down buck converter that provides high efficiency DC-DC conversion while operating over a wide temperature range. It meets multiple safety standards, and has a wide range of applications in automotive, consumer electronics and industrial fields.
