5 Pin Configuration and Functions
SNVS822A – DECEMBER 2012 – REVISED NOVEMBER 2014
Output pin of the current DAC that connects to the feedback node of the regulator.
Positive supply input. Operating voltage is 2.97 V to 5.5 V. It is recommended to add a small
1-nF or greater bypass capacitor from this pin to GND.
Precision enable input. The LM10011 will operate when the EN pin voltage exceeds 1.34 V.
MODE will set the VID operating mode. Connecting MODE to VDD will select a 4-bit parallel
interface. Connecting MODE to GND will select a 4-pin, 6-bit interface.
A resistor connected from SET to GND will set the start-up code (current) at the IDAC_OUT
pin. There are 16 different start-up codes to select from.
VID digital input. In 6-bit mode: Bit 0 when VIDS transitions low; Bit 3 when VIDS transitions
high. In 4-bit mode: Bit 0.
VID digital input. In 6-bit mode: Bit 1 when VIDS transitions low; Bit 4 when VIDS transitions
high. In 4-bit mode: Bit 1.
VID digital input. In 6-bit mode: Bit 2 when VIDS transitions low; Bit 5 when VIDS transitions
high. In 4-bit mode: Bit 2.
VID select line. In 6-bit mode: transition low selects lower 3 bits, transition high selects upper
3 bits and updates the IDAC_OUT current to reflect the present VID code. In 4-bit mode: Bit
Die Attach Pad. Not electrically connected to device, connect to system ground plane for
reduced thermal resistance.
