TPR-W25 series 0.25W DC/DC

Product catalog summary

Description: The TPR-W25 series consists of miniature, isolated 0.25W DC/DC converters in a SIP package, designed for space-critical applications in board-level power distribution. These converters feature high performance at a low cost, with benefits such as smaller size, improved efficiency, lower output ripple noise, and 3KVDC isolation.

Selection Guide: The series includes various models with different nominal input and output voltages, output currents, and efficiencies. For example, the TPR0505S-W25 model has a 5V input and output, with a maximum output current of 50mA and 70% efficiency. A suffix 'P' indicates continuous short circuit protection.

Input Characteristics: The converters support a range of input voltages depending on the model, from 2.9V to 26.5V.

Output Characteristics: The rated power is 1W, with voltage set point accuracy and load regulation varying by model. For instance, the TPR0505S-W25 model has a load regulation of 13%.

Absolute Maximum Ratings: These include short-circuit protection for 1 second, a lead temperature of 300°C for 10 seconds, and specific maximum input voltages for different variants.

Features: The converters are RoHS compliant, offer up to 80% efficiency, and operate within a temperature range of -40°C to 105°C. They have a power density of up to 0.90W/cm³ and are housed in a UL 94V-0 package material.

Isolation Characteristics: The isolation voltage is 3000VDC, with a resistance of 1GΩ at 1000VDC.

Temperature Characteristics: The operating temperature range is -40°C to 105°C, with specific derating above 85°C. Storage temperature ranges from -50°C to 130°C.

Mechanical Dimensions and Pin Connections: The converters are housed in a 7-pin SIP package with specific pin functions for input and output connections. Detailed mechanical dimensions and recommended footprint details are provided.
