DC-DC converters offer a wide variety of benefits: Compact size, low weight, high efficiency, low heat generation, and wide temperature ranges with low input and output ripple. They also offer flexibility with the ability to customize, adhering to your specific application requirements. Even more so, if the requirements are for a relatively low voltage source then a 78SR115VC DC-DC converter is the ideal solution.

The 78SR115VC is a regulated DC-DC converter with an output voltage of 15V and mean current limit of 10A, and a maximum output current (Iout) of 15A. The 78SR115VC offers a wide range of output levels that can be adjusted by the use of external components, depending on the application. It offers a wide input range of 4.8V to 16V which makes it suitable for various applications.

The primary benefit of the 78SR115VC is its ability to convert standard commercial power supplies into specialized medical and industrial application requirements. Its integration of age compensation and input overvoltage protection for optimal performance make it a reliable solution for under-voltage, over-voltage, and low or high temperature situations. Additionally, the 78SR115VC is suited for a wide range of medical and industrial applications including electric vehicle charging, UPS systems, industrial machine controls, high-definition audio amplifiers, and portable medical equipment.

The 78SR115VC works on the principle of step-down voltage conversion. It takes DC input and steps it down to a lower voltage DC output. This is achieved through the use of a high current, bipolar NPN/PNP transistor (HBP) or switching MOSFET transistors (MOSFET). The HBP consists of two transistors that are connected back-to-back to form one “turn”. This single turn is used to power the 78SR115VC. The MOSFET works on the principle of P channel and N channel FETs, which are used to regulate the current in the output stage.

The 78SR115VC is equipped with a range of features designed to act as over temperature protection, overvoltage control, and input power cycle protection. It also includes an adjustable current limit protection (CFLP) and an over-voltage protection (OVP). The adjustable CFLP feature is especially useful for applications requiring long life expectancy or a steady output current when operating at higher temperatures. The over-voltage protection (OVP) feature ensures the converter does not consume more than the intended current even in the event of an over-voltage situation.

For improved energy efficiency and lifespan, the 78SR115VC can be configured either in continuous or discontinuous conduction modes. Continuous conduction mode (CCM) is more efficient and results in higher performance due to its higher switching frequency. The 78SR115VC can be configured to operate in up to twelve different operating frequency bands ranging from 45k to 2.8MHz. By selecting the optimal operating frequency, the 78SR115VC can be easily adapted to any application demanding accurate voltage regulation.

The 78SR115VC is a reliable yet cost-effective DC-DC converter designed for a variety of applications. Its flexibility and high power density make it a great choice for electric vehicle charging, industrial and medical systems, and other special applications. The 78SR115VC can be easily integrated into existing applications, making it an ideal solution for applications where space and weight are major considerations.
