20 SDA SMBus Serial-Data Input/Output
21 DGND Digital Ground. Connect DGND to AGND and AGND1 externally close to the device.
22 DVDD Digital Power-Supply Input. Connect a 1µF capacitor from DVDD to DGND.
23 RSVD Reserved. Connect to DVDD externally.
24 DACOUT3
Analog Voltage Output of Internal 12-Bit DAC 3. Connect to TRIM, REFIN, or FB of a DC-DC module
or an LDO to adjust the power-supply output voltage. High impedance in shutdown.
25 AGND1 Analog Ground. Connect to AGND and DGND externally close to the device.
26 AVDD Analog Power-Supply Input. Connect a 1µF capacitor from AVDD to AGND.
27 DACOUT2
Analog Voltage Output of Internal 12-Bit DAC 2. Connect to TRIM, REFIN, or FB of a DC-DC module
or an LDO to adjust the power-supply output voltage. High impedance in shutdown.
28 RS1-
Differential Remote-Sense Input 1 Return of the DC-DC Output Voltage. Connect to the return terminal
at the load.
29 RS1+
Differential Remote-Sense Input 1 of DC-DC Output Voltage. Connect to the load terminal where the
output must be regulated.
30 RS1C Filter Capacitor for V SENSE Amplifier 1. Connect a 1µF capacitor from RS1C to AGND.
31 REFO Reference Output. Connect a 1µF capacitor from REFO to AGND.
32 RS0+
Differential Remote-Sense Input 0 of DC-DC Output Voltage. Connect to the load terminal where the
output must be regulated.
33 RS0C Filter Capacitor for V SENSE Amplifier 0. Connect a 1µF capacitor from RS0C to AGND.
34 RS0-
Differential Remote-Sense Input 0 Return of the DC-DC Output Voltage. Connect to the return terminal
at the load.
35 DACOUT0
Analog Voltage Output of Internal 12-Bit DAC 0. Connect to TRIM, REFIN, or FB of a DC-DC module
or an LDO to adjust the power-supply output voltage. High impedance in shutdown.
36 RS2C Filter Capacitor for V SENSE Amplifier 2. Connect a 1µF capacitor from RS2C to AGND.
— EP
Exposed Pad. Internally connected to AGND. Connect EP to the ground plane of the power supplies
for best temperature measurement performance.
