DC DC Converters

DC-to-DC converters are electronic circuits that convert a source of direct current (DC) from one voltage level to another. Such converters are also known as “voltage source converters”. Typically, they convert a DC input voltage to a higher or lower DC output voltage, although some configurations can also be used to convert from a higher to a lower voltage. Common topologies include buck converters, boost converters, buck-boost converters, Cuk converters, and SEPIC converters.

The high efficiency of the device and its small form factor make it suitable for many applications including medical, industrial, and telecom.

Application field

The SD02D4815A is ideally suited for many applications including medical, industrial, and telecom. It is well suited for medical applications where an isolated power conversion solution is required that is high efficiency and has low injection current. It is a great choice for industrial applications running at higher power levels that require an isolated power solution for various audio functions, ASICs, sensors, MCUs, and cameras. In telecom applications, the SD02D4815A finds use in powering the various modules used in radio, access and core registers, and wireless base stations.

Working principle

The SD02D4815A is based on SynQor’s DualQor® technology, which is an advanced isolated DC-DC topology that uses two synchronous buck converters to achieve high efficiency, low component count, and low output voltage ripple. The device utilizes a primary switch on the input side and a secondary switch on the output side to regulate the output voltage. When the input voltage is applied, the voltage is stepped down through a primary buck switch. The output of this switch is rectified and filtered by an input capacitor to create a DC voltage. This DC voltage is then transferred to the secondary side, where it is regulated by the secondary switch. The voltage on the output side is then regulated by the secondary switch and output capacitor.
