DC-DC converters are widely used in many applications and SRDB-07A120R is no exception. SRDB-07A120R is a full bridge, isolated DC-DC converter with a wide range of input voltage. It is designed for industrial and telecommunications applications that require reliable power conversion, high efficiency and excellent transient performance.

The SRDB-07A120R has a power rating of 120W and a maximum output voltage of 24V (±12V differential). It is designed to provide high efficiency up to 92%, with soft-start, short circuit protection and adjustable output voltage and current limits. The converter has a wide input voltage range, from 10V to 440V DC. It is also capable of operating in severe environmental conditions, with temperature ratings of -40°C to +105°C.

The SRDB-07A120R is a voltage-mode converter, which regulates the output voltage by controlling the duty cycle of the power switch. The converter consists of an input side, an output side and a control circuitry. The input side includes a rectifier bridge, EMI filter, and harmonic compensation network. The rectifier bridge converts the AC input voltage to a voltage level that is suitable for the DC-DC converter. The output side of the converter consists of a MOSFET H-bridge, an output filter, and a voltage regulator.

The control circuitry of the SRDB-07A120R controls the power switch of the output side. In this circuit, the voltage output of the converter is adjusted by adjusting the duty cycle of the power switch. By controlling the duty cycle, the output voltage of the converter can be adjusted through a feedback loop. The control circuit also has a soft start circuit, which reduces the load inrush most during start-up.

The SRDB-07A120R is highly efficient and reliable, making it a great choice for industrial and telecommunication applications. Its wide input voltage range allows it to be used in a variety of applications, while its adjustable output voltage and current limits give it the flexibility for different application requirements. Combined with its impressive 92% efficiency, the SRDB-07A120R is an ideal solution for efficient and reliable DC-DC power conversion.
