Typical Features
The document outlines the features of a DC-DC converter series, highlighting a wide input voltage range of 2:1, a typical transfer efficiency of 87%, and a switching frequency of 300KHz. It includes overcurrent and short circuit protection with self-recovery, input-output isolation, PCB mounting, and a metal case with low output ripple.

Input Specifications
The input voltage ranges are specified for different models, with a 2:1 ratio. Remote control options are available, with high-level or suspended states for ON and low-level or ground connection for OFF. Input under-voltage protection is included, with self-recovery.

Output Specifications
Output voltage accuracy is typically ±1.0%, with line regulation at ±0.2% and load regulation at ±0.5%. Ripple and noise levels vary based on output voltage, with dynamic response specified for a 25% nominal load step change. Output voltage adjustment is possible within ±10%, and the turn-on delay time is typically ≤200ms.

General Specifications
The switching frequency is typically 300KHz, with a maximum of 330KHz. Operating temperature ranges from -25℃ to +55℃, with storage temperatures from -40℃ to +105℃. The maximum case temperature is +100℃, and relative humidity ranges from 10% to 90%. The case material is metal, and isolation voltage specifications are provided for input-output and input-case scenarios. The meantime between failures is 200,000 hours.
