REC3-1209SRW/H6/A/SMD/CTRL

DC DC Converters

The REC3-1209SRW/H6/A/SMD/CTRL is a type of DC DC converter, which is used to convert voltage from one source to the required voltage value for a desired application. It is capable of converting an input voltage range from 3.3V to 12V into an output voltage range from 1.2V to 5V. It provides high power and fast conversion rate, thus making it an ideal solution for cost-sensitive applications.

Application Field

This DC DC converter is primarily used in small portable electronic systems including digital cameras, camcorders, PDA, shavers, personal digital assistants, GPS systems, power tools, LCD modules and PDAs, given its lightweight and compact size. The wide input voltage range and its high speed conversion rate make it a great solution for these applications. It is often used in automotive and industrial applications as well. As it is a DC DC converter, it can also be used to step up or step down DC voltage.

Working Principle

The working principle of the DC DC converter is based on the concept of Pulse Width Modulation (PWM). In this case, the input voltage is converted into a PWM signal and then rectified and conditioned to produce the required output voltage. The PWM signal is created using a control chip, which is responsible for controlling the width, in other words, the duration of the pulse cycle. This PWM signal is then feed through a filter, which adjusts the frequency and amplitude of the signal to ensure a clean output. The rectified signal is then filtered and regulated to produce the required output voltage.

In order to ensure reliability, the DC DC converter is designed with multiple safety features. It includes features such as over-current protection, over-temperature protection, short-circuit protection and voltage regulation. The device also includes a soft start feature, which helps to avoid the possibility of voltage spikes and power supply surge. Additionally, the efficient heat dissipation system ensures the device operates within its specific temperature range and provides added reliability.
