TP25DG series 25W DC-DC converter

Product catalog summary
Description: The TP25DG Series converters offer a rated output power of 25W with dimensions of 50.8x50.8x11.2 mm. They support wide input voltage ranges of 2:1 and 4:1, covering 9V-18V, 18V-36V, 36V-72V, 9V-36V, and 18V-72VDC. The converters achieve an accuracy of ±1% and are suitable for telecommunications, railway transportation, and instrumentation applications.
Features: Key features include 25W output power, over-current protection, fixed switching frequency, metal shielding, input under-voltage protection, and RoHS compliance. The converters operate within a temperature range of -40℃ to 85℃ and provide 1.5KVDC isolation.
Selection Guide: The document lists various models with different input and output voltage specifications, efficiencies, and current ratings. Models are available for both single and dual outputs, with efficiencies ranging from 81% to 87%.
General Characteristics: The converters have an isolation voltage of up to 1500 VDC and an insulation resistance of 100M Ohm. They are designed to withstand seismic vibrations and have an MTBF of 500,000 hours. Cooling is achieved through free air convection.
Output Characteristics: Voltage accuracy is maintained at ±1%, with line and load regulation at ±0.2% and ±0.5%, respectively. The converters feature over-current protection and a switching frequency of 300 KHz.
Input Characteristics: Startup voltages vary by model, with input under-voltage protection provided. The startup time for output rise is specified, and remote control capabilities are included.
Environmental Characteristics: The converters operate in non-condensing humidity conditions and have a storage temperature range of -55℃ to +125℃. The maximum case temperature should not exceed 105℃.
Mechanical Dimensions and Pin Connections: Detailed dimensions and pin connections for DIP packages are provided, with specific configurations for single and dual outputs.
Recommended Circuit: Circuit diagrams for single and dual output configurations are included, with recommendations for input and output capacitance to improve electromagnetic compatibility.
Using Attentions: The document warns against input reverse polarity, long-term overload, and exceeding maximum input voltage, as these can cause irreversible damage. Recommendations for input and output capacitance values are provided to ensure stability.

TP25DG Series RECOMMEND CIRCUIT Dual Output: Add input capacitance Cin is helpful to improve the electromagnetic compatibility, recommend Cin use 47 uF-100uF of the electrolytic capacitors. If the module connect to the digital circuits, please add the Cout、Cout1、Cout2. If Cout, Cout1, Cout2 value is too high or lower ESR, it will cause the module instable, The recommended value of Cout, Cout1, Cout2 should be 100 uF/A, the current here means the output current.
