JTD1524D15

DC DC Converters

DC-DC converters are devices used to convert a direct current (DC) voltage to a different direct current voltage. The JTD1524D15 DC-DC converter is a module based on synchronous rectification that can convert DC input voltage of 10.8V to a configurable output voltage of 1.2V to 12V, while operating at high efficiency. It can supply 10A of output current when the input voltage is at least 2V higher than the output voltage and can power a wide range of devices, including embedded systems, industrial and consumer electronics.

Application Field

The JTD1524D15 is ideal for low voltage applications, such as embedded systems and consumer electronics, as it can generate low output voltage while maintaining high efficiency. It is especially suitable for use in the automotive industry, where it can generate a 12V DC power supply in a vehicle. In addition, the high power density of the JTD1524D15, which is 17.4W/in³ is also advantageous in automotive applications. It can also be used in industrial applications, such as motor drives, where a 10A output current is required.

Working Principle

The JTD1524D15 is a synchronous rectified DC-DC converter, which works by using two switches with opposite AC voltages, such as the MOSFETs, transistors, or thyristors. The inputs of the switches are connected to the input voltage source and the outputs are connected to the DC output. When the switch closes, the input voltage is divided into two separate AC voltages, which is then rectified and regulated to get a DC output voltage. The output voltage can be adjusted by varying the duty cycle of the switching arrangement.

The JTD1524D15 also has several other features to ensure efficient operation. It has a peak current monitoring and limiter, and an over-current protection circuit that reduces the input current in overcurrent conditions. It also has a ripple rejection function, which reduces noise on the output voltage. The module is also thermally protected; it has an internal thermal protection circuit that shuts down the module when the temperature exceeds a certain limit.

The JTD1524D15 also has a wide range of protection features, such as output overvoltage protection, input undervoltage protection, and input surge protection. The module also has a built-in EMI filter, which reduces the electromagnetic interference generated by the module. Finally, the module is also designed to be compatible with most output capacitors, which enhances its reliability and ensures its performance.
