Description
The ISL95210 is a high-efficiency step-down regulator that can deliver 10A of output current from a 5V input. The small 4mmx6mm QFN package and only four external components provide a very small total solution size. Low resistance internal MOSFETs deliver excellent efficiency and permit full power operation in a +90°C ambient without airflow.
The regulator operates from an input voltage of 2.97V to 5.5V, and provides a 0.6% accurate output voltage over the full operating temperature range. Intersil's patented R4™ control architecture provides exceptional transient response with no external compensation components. The output voltage may be programmed by an internal DAC or by an external resistor divider (see "Output Voltage Programming" on page 11 for more details).
Several digital control signals provide flexibility for users that want additional features. Switching frequency, switching mode, output voltage margining and daisy-chained power-good functions are all programmed by these pins. The ISL95210 also includes comprehensive internal protection for overvoltage, undervoltage, overcurrent and over-temperature conditions.
