3.1.1 Test Setup

Load Transient measurements were performed in the four DC/DC converters using typical values for an SSD application. Every module was measured while the other modules had a constant load with the following operating values:

  • SoC 0.9 V – 2.0 A
  • NAND I/O 1.2 V – 1.3 A
  • NAND VCC 2.5 V – 1.7 A
  • SOC I/O 1.8 V – 10mA
