December 15, 2011 High Efficiency 5V, 10A Buck Regulator
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 +90В°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 R4в„ў 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). Features 10A Continuous Output Current 2.97V to 5.5V Input Voltage Range Up to 95% Efficiency Full Power Operation in +90В°C Ambient without Airflow R4в„ў Control Architecture Delivers Excellent Transient
Response Without Compensation Pin Selectable Output Voltage Programming В±0.6% Output Voltage Accuracy Over Full Operating
Temperature Range Programmable Enhanced Light-Load Efficiency Operation Several digital control signals provide flexibility for users that
want additional features. Switching frequency, switching
mode, output voltage margining and daisy-chained powergood functions are all programmed by these pins. The
ISL95210 also includes comprehensive internal protection for …
