Two 7-bit current DACs sink or source current from\/to an external FB node of a DC-DC converter, adjusting the output voltage above or below nominal. The MSB of each 7-bit value sets direction (sink\/source), the remaining 6 bits set magnitude. This enables \u00b1margin adjustment for power supply validation testing.<\/p>\n
