Paquete QFN-24 (7x4mm, integrated inductor)

Características

  • Integrated inductor — no external magnetic component required
  • 4MHz switching frequency for ultra-fast transient response
  • 0.6V-3.6V adjustable output for FPGA/SoC core and I/O rails
  • 93% peak efficiency with only 8mVp-p output ripple
  • Complete PowerSoC solution in a single 7x4mm QFN package
  • Internal soft-start, OCP, OTP, and UVLO protection

Aplicaciones

  • FPGA and SoC core and I/O voltage regulation
  • Point-of-load power for Altera/Intel FPGAs
  • Portable and space-constrained power supplies
  • High-density board power distribution

The EN5335QI from Intel is a 3A PowerSoC (Power System-on-Chip) synchronous buck converter that integrates the power MOSFETs, controller, and inductor into a single QFN-24 (7x4mm) package. This integration eliminates the need for external inductor selection, PCB layout optimization, and EMI filtering associated with discrete DC-DC converter designs. The 4MHz switching frequency provides fast transient response for demanding FPGA core rails, while the 93% peak efficiency and 8mVp-p output ripple deliver clean, efficient power in a fraction of the board area of traditional solutions.

The EN5335QI uses a current-mode synchronous buck topology operating at a fixed 4MHz switching frequency. The integrated inductor is fabricated using thick-film magnetic material deposited directly on the silicon die, providing the energy storage element without a discrete external component. The high-side and low-side MOSFETs are integrated on the same die as the controller, minimizing parasitic inductance and resistance in the power path. The current-mode control loop measures the inductor current directly and adjusts the duty cycle to maintain output regulation. The 4MHz frequency allows the control loop bandwidth to exceed 200kHz, providing sub-10µs transient recovery for FPGA load steps.
