Positive supply input. Operating voltage is 2.97 V to 5.5 V. It is recommended to add a small VDD 3 I 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 will set the VID operating mode. Connecting MODE to VDD will select a 4-bit parallel MODE 5 – 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 SET 6 – 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 VIDA 7 I 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 VIDB 8 I 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 VIDC 9 I high. In 4-bit mode: Bit 2. VID select line. In 6-bit mode: transition low selects lower 3 bits, transition high selects upper VIDS 10 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 DAP DAP – reduced thermal resistance. 6 Specifications 6.1 Absolute Maximum Ratings (1) (2) over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VDD, EN, IDAC_OUT, MODE –0.3 6 V VIDA, VIDB, VIDC, VIDS –0.3 6 V Junction Temperature 150 °C (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
