DC DC Converters

A DC DC converter is an electronic device which is used to convert a direct current voltage from one level to another level. It is a type of syncronous rectifier-based regulated power supply. DC DC converters are used in various applications, such as motor drives, power supplies, control systems, lighting, battery charging and more. The most common type of DC DC converter is the so-called “buck” converter, which operates on the principle of inductive circuit. Buck converters can convert higher DC voltages into lower DC voltages, or vice versa.

The JWE0624S05 is a DC DC converter from Johnson Electric, designed to convert a DC voltage of 12V to 24V, with a power of 5A. It utilizes a synchronous rectifier-based buck circuit, with a precision programmable output voltage which allows for a wide operating range. The JWE0624S05 operates in operating temperature range of -40°C to +85°C, and can deliver up to 5A of output current at an efficiency of 88%.

The JWE0624S05 application field ranges from motor drive systems to industrial power supplies, from LED lighting to UPS. Industrial applications include controls, servo systems, alarm panels, SCADA systems, HVAC systems, pumps, valve actuators, and other electronics.

The working principle of the JWE0624S05 is based on a mutual-inductance type synchronous buck-converter. The input voltage is rectified into DC, then fed to a transformer. The transformer output voltage is rectified and regulated by an IC, resulting in a regulated and stable output voltage. The output voltage resolution of the JWE0624S05 is 0.1V, which allows for a wide range of adjustment and settings.

The JWE0624S05 incorporates a unique circuit design which reduces the output ripple by up to 50%, and also has an automatic power shut-off/restart feature that boosts reliability and stability. The JWE0624S05 is also equipped with an over-voltage protection and current limit feature. The regulator is also safeguarded against short-circuiting and over-temperature, to ensure safe operation.

The JWE0624S05 is a highly efficient and reliable DC-DC converter, suitable for a wide range of applications, ranging from motor drives, to industrial power supplies, to LED lighting systems. It utilizes a reliable synchronous buck-converter, with a precision programmable output voltage, and a unique circuit design which reduces the output ripple by up to 50%. It also includes an over-voltage protection and current limit feature, and is safeguarded against short-circuiting and over-temperature.
