The Intel Enpirion® EN29A0QI 10 A PowerSoC module is designed to power supply rails requiring very low ripple, low EMI, and tight DC and AC accuracy, such as transceiver power rails. The device is optimized specifically to meet the very stringent requirements for H-Tile, L-Tile, and E-Tile transceivers for Intel FPGAs and accelerators, as well as transceivers for other FPGA and ASIC devices. The EN29A0QI provides high conversion efficiency while maintaining excellent accuracy.
The EN29A0QI sports a very high-performance control loop that enables a significant reduction in the bulk capacitor decoupling requirements. Bulk decoupling capacitors such as poly-tantalum or OSCON can represent reliability concerns, so reduction of these not only saves on cost and space, but also improves system reliability. The low impedance loop enables the use of thin film precision resistors which exhibit superior long-term stability and reliability. The EN29A0QI enables improved system-level reliability.
The EN29A0QI provides a high degree of programmability. This includes programmable switching frequency to allow the user to optimize the trade-offs between ripple and efficiency. Startup and shutdown timing is programmable and has a precision enable and POK to optimize sequencing. The device also features a bi-directional SYNC pin where a device can output a master clock, or synchronize to another EN29A0QI or an external system clock.
