The DTE2048S24 is a member of the DC-DC converters family. It is a compact, 10 watt, single output, programmable switch mode DC-DC converter. This device offers a wide variety of features including programmable output voltage and current limit, adjustable soft-start, undervoltage lockout, overvoltage protection, and integrated EMI filters.

The primary application field of this device is for applications that need a reliable, compact, and efficient DC power supply. It is suitable for use in communication equipment, industrial equipment, data storage systems, consumer electronics, and automotive systems.

The converter is a 3-phase full-bridge topology, which allows for constant power over a wide input voltage range. It uses a low-cost, low-jitter, high- efficiency synchronous rectification process, which provides high efficiency power conversion, and helps reduce cost and size.

The output voltage and current setting of the converter is done through programmable pins. The converter has a built-in controller that can detect the output voltage and current settings and will automatically adjust the duty cycle of the MOSFETs to achieve the desired voltage and current limit. The voltage/current limit setting has two independent modes of operation, slow rise and fast rise. In slow rise mode, the duty cycle and voltage/current limit is smoothly ramped up after the startup ramp is completed, allowing for smoother startup and fewer parasitic voltage spikes. In fast rise mode, the duty cycle is directly adjusted to the voltage and current limit setting.

The converter also has additional features such as adjustable soft-start, undervoltage lockout to protect against reverse-polarity or abnormal input voltage, overvoltage protection to prevent over-voltage damage to the converter, and integrated EMI filters to reduce EMI challenges. All these features help ensure reliable operation over a wide range of operating conditions.

The DTE2048S24 is a versatile, robust, and efficient DC-DC converter suited for a variety of applications. Its automatic voltage/ current limit and adjustable soft-start make it particularly useful for industrial and automotive applications. Its wide input range, high efficiency, and integrated EMI filters make the converter an ideal choice for communications and other sensitive data processing applications.
