This pin also provides the gate bias charge for all the MOSFETs controlled by the IC. The voltage at this pin is monitored for Power-On Reset (POR) purposes. DRIVE2 (Pin 2) Connect this pin to the gate of an external MOSFET. This pin provides the drive for the NVVDD regulator’s pass transistor. VID2, VID1, VID0 (Pins 5, 6 and 7) VID0-2 are the TTL-compatible input pins to the 3-bit DAC. The logic states of these three pins program the internal voltage reference (DACOUT). The level of DACOUT sets the VTT converter output voltage, as well as the corresponding PGOOD and OVP thresholds. PGOOD (Pin 8) PGOOD is an open collector output used to indicate the status of the output voltages. This pin is pulled low when the synchronous regulator output is not within ±10% of the DACOUT reference voltage or when any of the other outputs are below their under- voltage thresholds. VSEN2 (Pin 9) Connect this pin to a resistor divider to set the linear regulator (NVVDD) output voltage. |
