Connecting this pin to the output voltage makes the on-time propor- tional to VOUT. The comparator input defaults to 0.6V when the pin is grounded and defaults to 4.8V when the pin is tied to INTVCC. PGOOD (Pin 32/Pin 3): Power Good Output. Open drain logic output that is pulled to ground when the output voltage is not within ±10% of the regulation point, after the internal 25µs power bad mask timer expires. Exposed Pad (Pin 33) UH Package: Signal Ground. Must be soldered to the PCB ground for electrical contact and optimum thermal performance. PI FU CTIO S (UH Package/G Package) |
