DC DC Converters

The MEJ2S1515SC is a type of synchronous DC-DC converter that provides high power efficiency and outstanding dynamic performance. This series of DC-DC converters is designed to support mission-critical applications, such as in telecom network, medical devices, and automotive electronics.This DC-DC converter is capable of providing a wide input voltage range, from 4.5V to 18V, with an output voltage range of either 0.8 to 5V or 0.8 to 3.3V. It is capable of delivering a maximum output current of 15A with high power efficiency of over 95%, making it ideal for applications where high power delivery and efficiency are both essential.The MEJ2S1515SC is equipped with various protection features, such as input over-voltage protection, over-current protection as well as short-circuit protection. It also features in-rush current protection, which helps to limit the inrush current to prevent system damage caused by high in-rush current.To achieve a regulated output voltage, the MEJ2S1515SC utilizes the pulse width modulation (PWM) method, where a high-frequency series of pulses varying in width to control the power output of the DC-DC converter. By varying the duty cycle of the pulse width modulation, the output voltage is regulated to the desired level.To ensure optimum performance, the MEJ2S1515SC features a remote on/off control pin, allowing the DC-DC converter to be remotely controlled via an external signal. By connecting this pin to an external pull up/pull down resistor, the DC-DC converter can be controlled from off to on, or off to on and back to off again. This helps to improve system reliability as well as reduce power loss and conserve energy.The MEJ2S1515SC is suitable for a wide range of applications, including industrial, automotive, mission-critical telecoms and medical devices. Specifically, it can be used in supervisory control and data acquisition (SCADA) systems, automotive junction boxes, distributed power systems, etc. It is also suitable for automotive systems that require stricter protection, such as ABS, traction control, airbag, dynamic control units, fuel injectors, brake control modules, navigation systems, entertainment units, and more.To summarize, the MEJ2S1515SC is a high-efficiency, mission-critical DC-DC converter which can deliver 15A of output current and support a wide input voltage range, from 4.5V to 18V. This series of DC-DC converters features pulse width modulation (PWM) based regulation and an external on/off control, and is suitable for a wide range of applications, including supervisory control and data acquisition (SCADA) systems, distributed power systems, industrial, automotive, and more.
