High Efficiency 5V, 10A Buck Regulator
ISL95210
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.
