DC-DC converters are power electronic devices used to change the voltage level of a DC power source. An example of such a converter is the SUCS32412BP-G, a device which can provide the technical requirements of a variety of industrial applications such as automotive, aerospace, and communications. This converter is designed to work with DC voltages of up to 74V and provide regulated DC output ranging from 2. (0.2V adjustable) V to 24 V.

The SUCS32412BP-G is a high-efficiency, full-bridge DC-DC converter designed to work with non-isolated input and output. The device is a non-isolated module with a dominant feature that is a synchronous rectification, resulting in a much higher efficiency than its non-synchronous counterparts. The built-in PFC controller and feedback circuit achieve high power factors of up to 0.98. Maximum power conversion efficiency of the SUCS32412BP-G can reach up to 96.5%, providing a high power solution for demanding applications.

The core of the SUCS32412BP-G is two high-efficiency MOSFETs, which are the main appendages of the circuit. The conduction flow of these switch MOSFETs is determined by the Pulse-width modulation (PWM) and pulse frequency modulation (PFM) system, both of which are internal to the device. First, the PWM control senses the input voltage and adjusts the duty cycle of the switching MOSFETs. Second, the PFM control maintains the operation frequency of the switching MOSFETs in buffer. By regulating the voltage applied to the switching MOSFETs and the frequency of their operation, the device can deliver an output voltage according to the user’s required parameters.

The protection of the SUCS32412BP-G also plays an important role. The converter is equipped with multiple protection features, such as over-voltage/current protect and over-temperature protection, which make the device more robust when under extreme conditions. The device also has a built-in thermal shutdown lockout circuit, which shuts down the switching MOSFETs and enters a low-power idle state to protect the module against excessive current or temperature.

The SUCS32412BP-G is a versatile DC-DC converter which can meet the requirements of various applications, such as portable electronic devices, automotive systems, and industrial equipment. It features a good ratio between input and output voltage, a high power efficiency, and a comprehensive protection function, making it an ideal choice for power supply solutions.
