TPR-1W series 1W DC/DC

TPR-1W series 1W DC/DC

Product catalog summary

Description: The TPR-1W series consists of miniature, isolated 1W DC/DC converters in a SIP package, ideal 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 TPR0303S-1W has a 3.3V input and output with 303mA max current and 72% efficiency. Models with continuous short circuit protection are available by adding a 'P' suffix.

Input Characteristics: The converters support a range of input voltages from 3.3V to 24V, with specific voltage ranges for each input type. Isolation voltage is tested at 3000VDC for 1 second, with a resistance of 1GΩ at 1000VDC.

Features: Key features include RoHS compliance, up to 80% efficiency, operating temperatures from -40°C to 105°C, and a power density of up to 0.90W/cm³. The package material is UL 94V-0 certified, and the converters have CE certification.

Output Characteristics: The rated power is 1W, with various load regulation percentages depending on the model. The converters have a short-circuit protection duration of 1 second and can withstand lead temperatures of 300°C for 10 seconds.

General Characteristics: Switching frequencies vary by input voltage, ranging from 90 kHz to 160 kHz. The converters are cooled by free air convection.

Temperature Characteristics: The operating temperature range is -40°C to 105°C, with storage temperatures from -50°C to 130°C. Case temperature above ambient varies by output type.

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