Product Summary
The 88PG847BB1-NAM1C000 is an intelligent digital synchronous step-down switching regulator with on-chip low-drop-out regulator controllers housed in a 3mm × 3mm QFN-16 package. Internally self-compensated, the 88PG847BB1-NAM1C000 requires no external compensation and work with low-ESR output capacitors to simplify the design, minimize the board space, and reduce the amount of external components. The applications of the 88PG847BB1-NAM1C000 include: portable computering, disk drive power supplies, 3.3V PCI express bus.
