Fig. 3 - Pin Configuration - Bottom View PIN DESCRIPTION PIN NUMBER SYMBOL DESCRIPTION
1, 2, 3, 34 PVIN Input voltage for power stage 4 PH Phase node, return path of high side gate driver 5 GH High side MOSFET gate monitor 6 BOOT Bootstrap voltage for high side gate driver (referenced to PH) 7, 16 AGND Analog signal return ground 8 NC Not used in Vishay device 9 NC Not used in Vishay device 10 NC Not used in Vishay device 11 VSEN- Remote sense amplifier negative input connect to output ground 12 VSEN+ Remote sense amplifier positive input connect to output Power good; open-drain output indicating V 13 P OUT is within set limits. Connect a pull up resistor typically GOOD 10 kΩ to VDD 14 ADDR PMBus address programming pin 15 VSET Output voltage set point by connecting a resistor from VSET to AGND Clock synchronization pin. Frequency can be set by connecting a resistor to A 17 RT/SYNC GND. Pending on master / salve configuration, a clock can be send / receive via the pin 18 SALRT PMBus alert. Connect to external host interface if desired 19 SDA PMBus data. Connect to external host interface 20 SCL PMBus clock. Connect to external host interface 21 EN Enable pin. Active high 5 V logic level input 22 VDD Internal 5 V circuits supply voltage. VDD is a LDO output, connect a 1 μF decoupling capacitor to AGND 23 VIN Internal driver supply voltage Supply voltage for internal gate drive. PV 24 PV CC is a LDO output. Connect a 4.7 μF decoupling capacitor to CC PGND 25 GL Low side MOSFET gate monitor 26 to 31 SW Switch node 32, 33 PGND Power ground. Common return for internal MOSFETs
