ADDR1 11 I High order address pin for PMBus device. Connect a resistor to AGND (see Table 3). ADDR0 12 I Low order address pin for PMBus device. Connect a resistor to AGND (see Table 3). AGND 8 — Analog ground pin, used for analog signal. Connect to thermal pad directly. AVSCLK 10 I AVS clock AVSDATA 9 I AVS data 3.3-V bias power for logic. A low-ESR ceramic capacitor with a value of 0.33 µF or greater should be BP3 26 O connected closely from this pin or to AGND. The maximum suggested capacitor value is 10 µF. Output bypass for the internal regulator. A low-ESR ceramic capacitor of 1 µF or greater should be BP5 25 O connected closely from this pin to PGND pin. The maximum suggested capacitor value is 10 µF. Logic level input which starts or stops channel 1. An internal 6-µA current source pulls VCNTL1 up to VBP5 CNTL1 3 I when the pin is floating. Logic level input which starts or stops channel 2. An internal 6-µA current source pulls VCNTL2 up to VBP5 CNTL2 4 I when the pin is floating. COMP1 36 O Output of the error amplifier 1 and connection node for loop feedback components COMP2 15 O Output of the error amplifier 2 and connection node for loop feedback components Negative pin of current sense amplifier for channel 1. An internal, 4-k Ω resistor pulls CS1N to 1.24 V during CS1N 33 I smart power mode operation to provide a bias voltage required by smart power stage. CS1P 32 I Positive pin of current sense amplifier for channel 1 Negative pin of current sense amplifier for channel 2. An internal, 4-k Ω resistor pulls CS2N to 1.24 V during CS2N 18 I smart power mode operation to provide a bias voltage required by smart power stage. CS2P 19 I Positive pin of current sense amplifier for channel 2 DIFFO1 39 O Remote Sense Amplifier Output for channel 1 Inverting input to the error amplifier 1. In normal operation, the voltage on this pin is equal to the internal FB1 35 I reference voltage. Connect the FB1 pin to the BP5 pin to set the channel as slave channel.
