Pin Functions

PIN I/O DESCRIPTION
NAME NUMBER
GND 1 – Ground
IDAC_OUT 2 O Output pin of the current DAC that connects to the feedback node of the regulator.
VDD 3 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.
EN 4 I Precision enable input. The LM10011 will operate when the EN pin voltage exceeds 1.34 V.
MODE 5 – 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.
SET 6 – 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.
VIDA 7 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.
VIDB 8 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.
VIDC 9 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.
VIDS 10 I 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 3.
DAP DAP – Die Attach Pad. Not electrically connected to device, connect to system ground plane for reduced thermal resistance.
