DC-DC Converters

Dc-dc converters are devices used to convert direct current (DC) from one voltage level to another. The voltage level conversion of DC currents can be used for products, industrial applications or even powering small electronics. There are multiple types of dc-dc converters, such as switching, linear, and boost converters, each with its own set of features and benefits.

REC10-4815SRWZ/H3/A/M Application Field and Working Principle

The REC10-4815SRWZ/H3/A/M is a dual-output, step-down, non-isolated DC-DC converter. It is engineered for low electrical noise, high power density, and high-efficiency applications. It is suitable for industrial applications such as robotics, electric vehicles, industrial control systems, and for powering certain components such as sensors. The REC10-4815SRWZ/H3/A/M operates from a wide input voltage range of 4.5-36V DC and offers two adjustable output voltages of 0.6-5.5V DC. This DC-DC converter also features a high conversion efficiency of up to 97%.

The REC10-4815SRWZ/H3/A/M features a step-down, non-isolated voltage conversion mechanism. This is the process of dropping the input voltage to the desired lower output voltage. This unit utilizes a synchronous rectification method, which is more efficient than other volt-conversion methods. In this process, the circuit refers to an inductive element, such as a transformer, to produce a voltage step-down to meet the desired output voltage. When the transistor is in an “on” state, the electricity passes through it and charges the inductor. Once the inductor has reached a certain level of inductance, the transistor turns “off”, and the stored energy is released to the attached capacitor. This process helps to regulate the voltage and allow for a better flow of energy.

The REC10-4815SRWZ/H3/A/M’s current limit protection feature safeguards against overloading and short-circuiting. The output voltage is adjustable with an external resistor, and it is also capable of synchronizing with another REC10-4815SRWZ/H3/A/M unit. This unit is also reverse-polarity protected and also has overvoltage protection. This allows it to withstand voltage spikes and to protect against inadvertent changes in the input voltage.

The REC10-4815SRWZ/H3/A/M operates in temperatures ranging from -40C to +85C and has a package size of 11.8mm x 7.6mm x 2.5mm. It is also suited for mounting in tight spaces or areas with physical restrictions. Overall, the REC10-4815SRWZ/H3/A/M is highly suitable for low electrical noise, high power density, and high-efficiency applications such as industrial control systems, electric vehicles, robotics and more.
