The Marvell 88PG8237A1-NFE1C000 is a QFN-20 package, Synchronous Step-Down Converter. The Marvell 88PG82XX family integrates the dual synchronous Step-Down (Buck) switching regulators housed in a 3 X 4mm QFN-20 package. Internally self-compensated, the step-down regulator 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 step-down regulator 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. The 88PG82XX family operates from an input voltage range of 2.75V to 5.5V, making the device well suited for portable applications. Other key features of the 88PG82XX family include soft start, an internal current limit, an under-voltage lockout, thermal shutdown, over voltage protection, and power-on-reset signals.
