DESCRIPTION
Ground
O
Output pin of the current DAC that connects to the feedback node of the regulator.
I
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.
I
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.
I
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.
I
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.
I
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
I
3 bits and updates the IDAC_OUT current to reflect the present VID code. In 4-bit mode: Bit
3.
Die Attach Pad. Not electrically connected to device, connect to system ground plane for
reduced thermal resistance.
