EVB-EN63A0QI: 1.02V, 1.2V, or 1.8V @ 12A, 2.5 ~ 6.6V

Summary

The EN63A0QI is a Power System on a Chip (PowerSoC) DC to DC converter with an integrated inductor, PWM controller, MOSFETs and compensation to provide the smallest solution size in an 10x11x3mm 76-pin QFN module. It offers high efficiency, excellent line and load regulation over temperature and up to the full 12A load range.

The EN63A0QI is specifically designed to meet the precise voltage and fast transient requirements of high-performance, low-power processor, DSP, FPGA, memory boards and system level applications in distributed power architecture.

The EN63A0QI features switching frequency synchronization with an external clock or other EN63A0QIs for parallel operation. Other features include precision enable threshold, pre-bias monotonic start-up, and programmable soft-start. The device’s advanced circuit techniques, ultra high switching frequency, and proprietary integrated inductor technology deliver high-quality, ultra compact, non-isolated DC-DC conversion.

Jumpers are provided for logical programming of the following signals:

  • ENABLE (ENA)

  • Master/Slave ternary input (M/S)

  • Enable Pre-Bias Input (SEL)
    Enable may also be controlled using an external switching source by removing the jumper and applying the enable signal to the connector middle pin and ground.

  • Jumpers are also provided for getting various output voltages.
