Rev. 0206 Sipex’s PowerBloxTM Family offers high voltage capability in an ultra-small package! Applications Include: Easy to Use Ultra-Miniature Power Up Protocols Sipex developed PowerBlox to enable designers to create a quick and easy power system with the fewest number of external size components. This family of high current, Actual 4mm high voltage, ultra-miniature DC/DC buck 7mm x regulators greatly simplifies the complex task of designing power solutions for next generation electronics applications. • Sipex's unique package technology produces the industry’s smallest 8A component, measuring a mere 7mm x 4mm. By offering various power up protocols, Sipex PowerBlox ICs eliminate the use of sequencing control ICs, simplifying system design and reducing costs. Depending on your design requirements, you can choose simultaneous, sequential or ratiometric power up, using a proprietary chip-to-chip interface. • The part is packaged in a custom DFN package with three integrated heat sinks for outstanding thermal management. High Efficiency Simultaneous Power Up • With integrated high performance, low resistance MOSFETs, the PowerBlox family achieves up to 95% efficiency, surpassing all competing solutions. • Cable Modems • Industrial Applications • Set Top Boxes • DC to DC Power Supplies • Plasma TVs • Medical • LCD Monitors • FPGA Power Supplies • Robotics • Automated Test Equipment • Routers • DataCom Equipment All converters begin their soft start cycle simultaneously, with the same slew rate. VIN 25V 5V VIN 3.3V • Even at high load, the family is able to maintain an impressive level of efficiency, thus minimizing heat dissipation and energy loss.
