DC to DC converters, also known as DC DC converters, are electronic circuits used to convert a DC voltage from one level to another. They are common in a variety of applications, including the automotive, military, aerospace, and industrial industries. The DG06D4812A is a high efficiency, full-bridge, phase-shifted DC-DC converter that offers a unique, space-saving design for high power applications up to 20A.

The DG06D4812A has a synchronous rectification topology that combines the current rating of a high frequency, full-bridge topology with the efficiency of a phase-shifted full-bridge topology. Using only two low RDS(on) MOSFET switches, the DG06D4812A is able to achieve up to 97.8% efficiency for applications where high load current and low output voltage ripple is desired. The converter is designed to accept a DC input voltage from 4.5V to 24V and is capable of delivering a regulated output voltage in the range of 0.6V to 12V.

The DG06D4812A utilizes a unique Synchronous Phase Shift (SPS) technique to reduce switching losses, thereby improving efficiency and lowering customers’ total cost of ownership. Furthermore, the built-in protections of Under Voltage Lockout (UVLO), Over Current Protection (OCP), and Output Short Circuit Protection (OSCP) make the DG06D4812A a reliable and safe power solution for automotive, industrial, aerospace, and military applications.

In terms of performance, the DG06D4812A features a fast transient response time of less than 1µs, a low EMI, and an output voltage accuracy of ±1%. The converter has an enable pin input, which simplifies the control of the converter and improves system reliability. The soft-start function further reduces the inrush current by slowly increasing the output voltage. The converter is housed in a 10mm x 12mm QFN package and is qualified according to AEC-Q100 Grade 1 Standard.

The DG06D4812A’s working principle is based on the principle of synchronous rectification. The input voltage is fed into the primary winding of a transformer, which transforms the voltage to the secondary side. The voltage is rectified by a bridge rectifier, which converts the AC output of the transformer to a DC voltage. This voltage is then regulated by a MOSFET switch. The switch is controlled by a PWM signal, which is generated by a control IC. This signal is used to adjust the on time of the MOSFET switch to regulate the output voltage.

The DG06D4812A is an ideal solution for applications where high power density and high efficiency in a compact form factor are required, such as automotive, industrial, military, and aerospace applications. The converter is available in both production and prototype quantities and is supported by a dedicated application engineering team to assist customers with their applications.
