Product Summary
The 88PG8227 is a Field Programmable DSP Switcher. The 88PG8227 integrates the dual synchronous Step-Down (Buck) switching regulators housed in a 3 X 4mm QFN-20 package. Internally self-compensated, the 88PG8227 requires no external compensation and works with low-ESR output capacitors to simplify the design, minimize the board space, and reduce the amount of external components. The switching frequency for the 88PG8227 is 1MHz, allowing the use of low profile surface mount inductors and low value capacitors. Each step-down regulator includes programmable output voltage to allow the user to easily set the output voltage with external resistors, logic control, or serial data interface. The output voltage range is 0.72V to 3.63V.
