JCD0512S15 Power Supplies - Board Mount

DC-DC converters are essential to the modern electronics industry. Everywhere in the world, power supplies that efficiently convert direct current (DC) from one voltage to another are used in many applications, ranging from medical to automotive, from consumer to industrial. One example is the JCD0512S15. This efficient DC-DC Step Down converter provides a regulated output voltage from an input voltage that is between 4.5V and 26V.

The JCD0512S15 requires an input voltage of 6.5V-26V to generate its 5V-15V adjustable output voltage. The switching frequency is fixed to 380kHz. The LED indicator lets you know when the power is on, and its low quiescent current allows the converter to be used in applications where low power consumption is essential.

The switcher architecture of the JCD0512S15 reduces cost and power losses. It also features a low profile surface mount design and requires no external breakout or cooling. Its sealed design makes it impervious to dust and other airborne contaminants. Additionally, it features over current protection and over temperature protection.

The specific application requirements often determine the type of converter chosen. High current step-down converters such as the JCD0512S15 are typically used to convert a higher input voltage into a lower regulated output voltage, without needing an external transformer winding. The JCD0512S15 can supply up to 3A output current with an input voltage of 6.5V-26V, and is efficient up to 88%.

The basic working principle of any DC-DC converter is to connect a small output stage to a large input stage. This is done with the use of a transistor or switch, resulting in current being drawn from the input stage, passing through the transistor to the output stage. As the current passes through the transistor or switch, its voltage is converted from higher input voltage to the lower output voltage. The output voltage is regulated by a control module, which adjusts the voltage as necessary to maintain a constant output.

The JCD0512S15 is a single-channel DC-DC step-down converter, offering an adjustable output voltage ranging from 5V to 15V with an input voltage of 6.5V to 26V. It is highly efficient, with a maximum efficiency of 88%. Its low profile surface mount design, over current protection and over temperature protection make it an ideal choice for a variety of applications.
