TPA2

Product catalog summary

Description: The TPA series consists of miniature, isolated 1W DC/DC converters available in SIP and DIP packages. These converters are designed for space-critical applications, offering high performance at a low cost. Key features include a compact size, improved efficiency, reduced output ripple noise, and 3KVDC isolation.

Selection Guide: The series includes various models with nominal input voltages of 24V and 48V, offering output voltages ranging from 5V to 24V, with efficiencies up to 81%. Models are available in both single and dual output configurations.

Input Characteristics: The input voltage range for 24V variants is 22-27V, and for 48V variants, it is 44-53V.

Output Characteristics: The rated power is 1W, with a voltage set point accuracy defined by a tolerance envelope. Line regulation is 1.0-1.2%, and load regulation varies by output voltage.

Features: The converters are RoHS compliant and CE certified, with a power density of up to 0.86W/cm³. They do not require a heat sink and offer 3KVDC isolation. The operating temperature range is -40ºC to 105ºC.

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

General Characteristics: The switching frequency is 110kHz.

Temperature Characteristics: The operating temperature range is -40ºC to 105ºC, with storage temperatures from -55ºC to 150ºC. Cooling is achieved through free air convection.

Soldering Information: The series is compatible with RoHS soldering systems, with a peak wave solder temperature of 300ºC for 10 seconds.

Absolute Maximum Ratings: Short-circuit protection is available for 1 second. The maximum lead temperature is 300ºC, and internal power dissipation is 450mW. Maximum input voltages are 28V for TPA24 and 54V for TPA48.

Mechanical Dimensions and Pin Connections: Detailed dimensions and pin connections are provided for both 14-pin DIP and 7-pin SIP packages. The recommended footprint details are also included.
