ADDR 1 I PMBus address configuration pin. Connect this pin into a resistor divider between VREG and GND to program different address settings ALERT 26 O Alert output for the PMBus interface EN 3 I The enable pin turns on the DC-DC switching converter. FB 23 I VOUT feedback input. Connect this pin to a resistor divider between the VOUT pin and GND. GND 22 G This pin is the ground of internal analog circuitry and driver circuitry. Connect GND to the PGND plane with a short trace (For example, connect this pin to the thermal pad with a single trace and connect the thermal pad to PGND pins and PGND plane). MODE 21 I The MODE pin sets the forced continuous-conduction mode (FCCM) or auto-skip mode operation. It also selects the ramp coefficient of D-CAP3 mode. NC 5 — Not connected. These pins are floating internally. 18 PGND 10 G These ground pins are connected to the return of the internal low-side MOSFET. 11 12 13 14 PGOOD 2 O Open-drain power-good status signal which provides startup delay after the FB voltage falls within the specified limits. After the FB voltage moves outside the specified limits, PGOOD goes low within 2 µs. SCL 28 I Clock input for the PMBus interface SDA 27 I/O Data I/O for the PMBus interface |
